Auto Johnny is ready to hit the streets, and I need a playable prototype that shows the core loop of a 3D endless runner on Android, built in Unity. Gameplay • Endless forward motion with tap/ swipe controls for left, right and jump. • Obstacles are moving and parked cars; feel free to stub-in other hazards later but cars are the must-have for this first pass. • Coins appear in a straight line down the centre lane so the player can weave in and out to collect them. • Running score that adds one point per coin and tracks distance. Look & Feel The whole scene should read as a bright, cartoonish city: low-poly buildings, bold colours and exaggerated proportions that match the auto-rickshaw hero vehicle. Quick looped traffic ambience plus simple c...

I’m building an educational multiplayer quiz platform aimed squarely at students, and I need clear, upbeat copy that keeps them clicking while subtly reinforcing learning. The site structure is simple—just four core pages plus a growing blog section—but every word has to pull its weight in search as well as in the classroom-style experience I’m offering. Here’s exactly what I’m after: • Four page-length pieces of website copy (Home, How It Works, About, and FAQ/Support) written in a casual, engaging voice that still feels trustworthy for an academic setting. • An initial set of short blog articles (propose 3-5 topics) that can spark ongoing content marketing and internal-link opportunities. • Full on-page optimisation for ever...
I want to build a SnapSell-style web platform where creators can upload digital files, set a price, generate a paid access link, and buyers can unlock the content after a one-time payment. Important: For the first version, I only want a web app / responsive web platform. No native iOS or Android app is required for the MVP. The system should be built in a way that mobile apps can be added later. The goal is similar core functionality to SnapSell, but with a custom and more premium design. Do not copy SnapSell’s branding, logo, UI, or copyrighted assets. Core MVP Features: 1. Creator Account - Sign up / login - Basic creator profile - Password reset 2. Content Upload - Upload files such as videos, images, PDFs, ZIP files - Secure file storage - File preview / teaser mode -...
My Android app is functionally complete and I already hold an active Google Play Developer account. What I am missing is the final stretch: creating the properly signed APK/AAB, validating everything against Play Console requirements, and getting the release live on the Indian Play Store. Here is where I need your expertise: • Review my existing source/build to confirm it meets current target-SDK, policy and security guidelines. • Configure a secure keystore and sign the build. • Generate the final APK or (preferably) AAB, run a quick check on install size and bundle integrity. • Walk me through (or directly handle) the console upload, content rating, privacy-policy link, screenshots, and rollout to production or staged track—whichever is fastest w...

The goal is to shape a fast-paced action title for iOS and Android from the ground up. I already know it will be a mobile game in the action genre; everything else is open for creative exploration, including whether first-person, third-person, or a top-down camera best suits the core loop. You will help me turn my rough vision into a complete, production-ready concept: articulate the story hook, define the main mechanics, map out progression, outline monetisation that feels fair, and recommend a visual style that matches the intended audience. I expect you to draw on tools you are comfortable with—Unity or Unreal for rapid prototyping, Figma or Illustrator for UI mock-ups, Blender or similar for visual references—whatever communicates the idea clearly. Deliverables I...
...lean, cross-platform AR app that can read a QR code, fetch the referenced 3D asset, cache it locally, and immediately overlay it on the live camera stream. Both Android (ARCore) and iPhone (ARKit) must be supported with identical behaviour and a clean, clutter-free UI. 3D assets will be supplied by me in the correct resolution and format; you will not need to create or optimise the models, only render them accurately in real scale. My preference is to bundle these assets inside the app so the experience works offline, but if package size becomes an issue I will give you access to a small HTTPS server from which the files can be downloaded on first launch. Core flow I am after: 1. The user points the camera at a QR code. 2. The app resolves the code into a s...
I have a website running on a Node back end and I’d like it available as native-feeling apps on both iOS and Android. My preference is to use React Native so we can share one codebase while still meeting Apple App Store and Google Play Store guidelines. Scope • Re-create—or wrap, if more efficient—the existing website in React Native. • Ensure full feature parity; no new features are required beyond accurately translating the current experience into an application. • Configure everything needed for App Store and Play Store submission, including icons, splash screens, provisioning profiles, signing, and build uploads. • Provide clear instructions or a short walkthrough so I can manage future updates myself. What I’ll supply &bul...
My Android application is already live on Google Play and I now need focused help with app updates and maintenance—specifically, adding a new feature and publishing the revised build through the Play Console. Here’s what I’m looking for: • Implement an agreed-upon new feature within the existing codebase. • Prepare a signed AAB/APK, update versioning, and upload it to the Play Store. • Complete the release process (closed test → staged rollout) and confirm the update is approved and visible to users. Clean, well-documented code and backward-compatible implementation are important to me. If you’re comfortable working with the latest Android SDK, Gradle, and Play Console workflows, let’s discuss the feature scope ...
...run smoothly on both iOS and Android, sharing one code-base if possible to keep future maintenance simple. Security is paramount. Access to the lock/unlock button must be protected by built-in biometric authentication—Touch ID, Face ID, or each platform’s native fingerprint solution. No PINs or passwords; the user experience should be instant once authentication succeeds. You will be integrating with the vehicle’s existing keyless entry module, which communicates over Bluetooth Low Energy. I can supply the BLE characteristics and sample packets; you will handle scanning, pairing, and encrypted command transmission. Expect a lightweight backend or local secure storage for managing paired vehicles and revoking keys. Deliverables • Production-ready i...
...GPS fix. Scope and expectations • Platforms: one code-base, runnable on both iOS and Android. I’m open to React Native, Flutter, or another cross-platform stack if it keeps maintenance simple. • Look & feel: crisp, modern visuals with intuitive gestures and minimal clutter. • Core features: real-time compass navigation, waypoint creation/management, and a dedicated “return to car” button that always sits one tap away. • Extra functionality I definitely need in this build: – Offline map tiles so the user can see terrain and streets without data. – Optional voice prompts (“You’re drifting 10° east of target,” etc.). – Configurable speed-limit alerts drawn from the map data....

...ready to see it running live on Google Cloud. All source code and assets are complete; what I need is the cloud architecture, deployment, and ongoing run-time configuration so the app launches smoothly on both iOS and Android. Here’s what I’m looking for: • Translate my current AI Studio project into a production-ready setup on Google Cloud (App Engine, Cloud Run, Firebase, or whichever service stack you recommend). • Configure the build so I can publish future updates with a single command, ideally through Cloud Build or a similar CI/CD pipeline. • Set up the required mobile back-end services—datastore, API endpoints, storage buckets, environment variables, and basic monitoring—so that the app’s features work right away wi...
Hiring: Full-Stack Mobile App Developer (iOS & Android) + Admin Panel + Backend System Only serious applicants should contact. We are looking for an experienced freelancer or development team to build a large-scale social audio platform from scratch. This is a full production-level platform, not a simple application.

...my AI-driven mobile application and need a fresh set of eyes to run thorough functional testing on the Android build. The goal is simple: help me uncover workflow breakers, UI glitches, and edge-case crashes before we push to production. Scope • Install the latest APK I provide (built for Android 10+) • Work through every screen, feature, and setting exactly as an end user would—text generation, voice interaction, in-app purchases, and account sync are priority paths • Log each issue with clear reproduction steps, screenshots or screen-videos, and your expectation versus actual behaviour • Retest fixed items within 24 hours of receiving a new build Right now I’m focused on Android only. If this collaboration goes smoothly I&...
...easy-to-pick-up game, I’m open to both paths. The key is that it must be fully store-ready: clean code, no policy violations, and attractive enough to earn downloads. Per finished project that meets the criteria below I can release ₹1,500 – ₹2,000, so feel free to pitch multiple ideas if you work fast. Deliverables • Signed release AAB or APK, ready for upload • Complete source code (Android Studio Java/Kotlin or Unity/C# are both fine) • Simple icon, screenshots, and a short store description • Confirmation that all assets are licence-free or originally created . Need to publish the app on the playstore too. Acceptance checklist • Compiles without errors or warnings • Runs smoothly on current Andr...
The goal of this project is a full-featured, endless-runner for Android that captures the fast, swipe-based flow of Subway Surfers but reimagined with crisp, retro pixel art. The core loop is a three-lane subway track where the player dodges trains, slides under barriers, leaps over gaps and collects coins. Key requirements • Visual style must be pure pixel art—from characters and environments to UI. • Android is the sole release platform; the build should target the latest stable SDK and run smoothly on mid-range devices. • Gameplay needs integrated power-ups and boosts (magnet, coin multiplier, speed burst, etc.) plus a character-customization menu where skins, outfits or colour palettes can be unlocked with in-game currency. • Basic ana...
I already run a live Android application that connects customers, delivery partners, and my operations team. The core product works, but it now needs a thorough upgrade so the entire ecosystem feels faster, smarter, and easier to use. The first milestone is a solid maps integration focused on real-time tracking. I want users to follow their delivery icon live, view accurate ETAs, and see driver movement without noticeable lag. If you have experience with Google Maps SDK (or any other mapping stack that can plug into Android) and have solved the usual battery, accuracy, and rate-limit issues, you will feel right at home here. Beyond maps, the release must include: • Refreshed customer, admin, and delivery-partner panels tied together through clean, well-documented backe...
...iOS and Android in a clean, intuitive interface. The app must let a salesperson: • Check real-time inventory levels before committing to a sale • Create and confirm sales orders on the spot, with totals and taxes calculated by Odoo • View and update customer details, contacts, and visit notes that sync back to Odoo automatically Because everything already lives in Odoo, the app has to authenticate with the same database and use native Odoo APIs (REST / JSON-RPC) so information flows both ways without manual export-import. I am open to the development stack—Flutter, React Native, Kotlin/Swift, or any other mobile framework—as long as the end result is two polished apps delivered through TestFlight and an Android APK for final store submiss...
...to the apps. • Native iOS and Android apps that let the home owner monitor all devices in real time, issue remote commands, and arrange their own dashboards with drag-and-drop widgets. The desktop tool must feel familiar to anyone who already works with TwinCAT yet remove the scripting overhead; point-and-click mapping, visual dashboard design, and one-click deployment are essential. For the runtime, I need solid connectivity to Beckhoff ADS/TCP, WebSockets for live updates, and a lightweight containerised build that can run on x86 or ARM. The mobile apps should mirror the dashboards created on the desktop, push instant status changes, and keep working over cellular or Wi-Fi with secure authentication. Your deliverable is the full ecosystem: source code, build ins...

My Flutter application is feature-complete but still plagued by a mix of UI/UX and performance issues that show up on both Android phones and iPhones. I need a developer who can dive into the existing codebase, isolate the root causes, resolve them cleanly, and then guide the project all the way through successful publication on Google Play and the App Store. You’ll investigate and correct the visual glitches, layout oddities, and navigation rough edges that are hindering a smooth user experience. At the same time, I expect you to profile the app, trim any performance bottlenecks, and make sure it launches fast, scrolls smoothly, and runs without memory leaks or unexpected slow-downs. Once the fixes are stable, I’ll count on you to prepare production builds, configure ...
I’m ready to move from concept to a working React Native mobile app that lets customers browse products, add them to a shopping cart, and check out—all behind a secure email-and-password login. The core of the job is to deliver clean, maintainable React Native code that runs smoothly on both iOS and Android. Here is what I need from you: • Build the front-end screens and flow for a modern e-commerce experience, including product browsing and a fully functional shopping cart. • Implement user authentication with email and password, handling sign-up, sign-in, and password reset screens tied to a backend of your choice (Firebase, Supabase, or a lightweight Node/Express API all work for me as long as the integration is documented). • Wire the UI to liv...
...32-inch and 43-inch commercial Android TV line and need a seasoned embedded hardware engineer who has already taken high-speed boards into production. My preference is to base the design on an Amlogic SoC, yet I’m willing to consider Realtek or MediaTek if you can justify the choice. The board must accept both LVDS and eDP so it can drive either panel size without revision. Core functions I require include 2–3 HDMI inputs, USB, wired LAN, Wi-Fi, audio out and a straightforward IR interface, all powered from a single 12 V feed with on-board regulation to 5 V, 3.3 V and any rails the SoC demands. Whether you start from a reference design, a compute module or a clean-sheet schematic is up to you; the end goal is a reliable board ready for mass production and Android...
...Application�—for the Android platform with a high level of fidelity. The goal is to match the flow, visual feel, and performance of the original while integrating three non-negotiable features: • Robust user authentication (email, social, or phone login—whatever mirrors the reference best) • Fully functional in-app purchases that follow Google Play billing guidelines • Timely, configurable push notifications I will provide design assets, a feature-by-feature breakdown, and access credentials needed for testing. In return, I expect: • An installable APK and complete, well-commented source code • Brief setup notes so I can run the project locally • A quick walkthrough video or call once everything is ready for hand-over ...
...and infrastructure company operating across multiple branches and project sites. The purpose of the platform is to provide one central digital system for collecting emissions-related operational data, automatically calculating CO₂ emissions, and generating dashboards, analytics, and reporting. The system should be accessible through: Web platform (desktop/browser) Mobile UI (applications for Android and iOS) Both web and mobile applications should be fully connected to one central cloud database and calculation engine, so all branches work within the same platform. Core Functions The platform should calculate CO₂ emissions from operational areas such as: Fleet & transportation Construction equipment & machinery Building materials (cement, steel, concrete, asphalt...
I record short clips on my Android phone and need them shaped into something worth sharing. For YouTube, the main job is to trim the raw footage, clean up any obvious rough cuts, and burn in subtitles that pop with color and light effects—nothing fancy, just eye-catching and easy to read. I will provide the script or a rough transcript so timing the captions should be straightforward. Alongside that, each video usually has one or two matching Instagram pieces. Those square or vertical posts need quick text overlays, light filters, and effects that fit the overall vibe of the video. Think of them as teaser clips or thumbnail-style images that entice people to click through. My budget is tight, so the workflow has to stay simple: quick turnaround, minimal back-and-forth, small...
...WordPress-based news site and want to turn it into a pair of Android apps—one for the public and one for my field reporters—while keeping the existing WordPress installation as the single source of truth. Here’s the vision • User app Readers open the app, browse stories by the same categories that exist on the website, receive push notifications for breaking headlines, and leave comments that sync back to WordPress comments. • Reporter app Accredited reporters log in, file stories with photos or video directly from their phones, track the editorial status of each submission, and get push alerts when an article is approved, needs edits, or goes live. Key points – Android only for the first release, but I’d like the cod...
I’m building a new mobile experience called CLAUDE: a personal productivity hub that travels seamlessly between iOS and Android. The core of the project is a robust task manager that syncs perfectly with the user’s calendar so that every to-do automatically lands in the right time slot, sends reminders, and updates in real time across devices. Scope of work • Design and develop the full app for both platforms—one shared code-base is preferable (Flutter, React Native or similar) to keep updates simple. • Implement intuitive task creation, prioritisation, drag-and-drop re-ordering and smart filters. • Integrate native calendar APIs (Apple, Google) so events and tasks coexist in a single timeline. • Set up secure cloud sync and basi...
I'm rebuilding the entire server side of my Android and iOS apps in Node.js. The current apps talk exclusively to a set of RESTful endpoints, and those endpoints handle three critical jobs for me right now: authenticating users, processing payments (using the CCAvenue gateway), and keeping local data in sync with the cloud. We also use WooCommerce custom REST API and its database for other core functions (products, orders, etc.) — but payments go through CCAvenue, not WooCommerce. I want every one of those workflows reproduced in Node so I can move faster with new features and scale without the legacy overhead. You'll have full freedom to modify the back-end codebase, database schemas, and deployment scripts as needed. All existing REST routes must remain available...
...the next several months. The immediate need is to design and implement RESTful APIs that handle user authentication and authorization, data retrieval/manipulation, and a handful of third-party integrations. Most of our existing micro-services are written in Python and Java, with a few high-performance components in Go, so the more comfortable you are jumping between those languages the better. You’ll be expected to: • Draft an endpoint specification we can review together. • Build the services in clean, idiomatic Python, Java, or Go (your choice per module), following REST best practices. • Wire in secure auth (JWT, OAuth2, or similar) and role-based access control. • Integrate external services where required, shielding the core logic behi...
Project Details 1. Project Overview(Backend Microservices System (SPRING FRAMEWORK ONLY)) We are developing a large-scale, enterprise-level digital commerce platform on a Java-based microservices architecture (Spring Ecosystem). The development phase is "LARGELY COMPLETED". We are not looking for a builder to start from scratch, but rather a "finisher"—a skilled Backend Engineer to take ownership of the existing codebase. The primary goal is to validate current integrations, stabilize the logic, and ensure the system is production-ready through rigorous testing. WE WILL PROVIDE TESTING HELP FROM OUR SIDE TOO. 2. Current Project Status & Scope The following microservices have been developed. Your role is to ensure these services communicate seamlessly,...
I need a series of concise tutorial videos that clearly demonstrate my code in action. The goal is to help brand-new customers understand how each feature works, so the recordings should feel welcoming and straightforward even for someone seeing the product for the first time. Each video will focus on a single feature walkthrough—from opening the project, stepping through the relevant functions, to showing the finished result—highlighting practical use rather than deep theory. Good screen-capture quality, a clean voice-over, and on-screen callouts where helpful will make the explanations land. Please deliver the finished MP4s plus any editable source files you use (e.g., Premiere, Final Cut, Camtasia, or similar). If you include short intro/outro bumpers or caption...
...mobile apps that work smoothly on both iOS and Android. The core of the job is to design, build, and deploy the entire application stack—mobile front-ends, backend services, and the basic infrastructure required for secure sign-up, real-time interactions, and ongoing content updates. Here is what I already know for sure: • Target platforms: Both iOS and Android, released to the App Store and Google Play. • App category: Social Media. Everything else—from interface details to feature roadmap—will be shaped with your guidance. I am looking for modern, maintainable code (Swift/Kotlin or React Native/Flutter are all acceptable), clean UI/UX, and a scalable backend architecture that can grow as the user base expands. Deliverables I expect: ...
...experience silky-smooth across iOS and Android. Top focus: build new features integrated with our REST and GraphQL services. While you’re at it, you’ll also tackle the bug list and squeeze every bit of performance you can out of React Navigation, Redux state, and our media-heavy screens. We already ship through Git-driven CI/CD, so comfort with version control, TestFlight/Play Store pipelines, and crash/performance debugging tools is important. Expect to work with push notifications, location services, and the occasional native module as well. Deliverables • Production-ready account management module, fully wired to backend • Resolved high-priority bugs with clear commit history • Documented performance gains (startup time, memory use, FPS) Cl...
