I want to see my site climb the SERPs quickly and sustainably by combining proven search-engine-optimization tactics with Generative Engine Optimization. Your job is to orchestrate both: the classic groundwork that wins Google’s algorithm today, and the prompt-engineering, structured data and content tuning that helps large language models surface my pages tomorrow. Scope of work • Run a full technical SEO audit, flagging and fixing anything that could throttle organic visibility. • Build a keyword map that targets ranking gaps and aligns with my business priorities. • Optimise on-page elements—titles, H-tags, internal links, schema markup—while weaving in GEO signals so AI engines can parse and recommend the content. • Produce or refre...

I need a full MATLAB/Simulink model of a single-phase, grid-connected photovoltaic system that lets me plug in my own DC-DC boost converter topology and then closes the loop with a Proximal Policy Optimization (PPO) controller. The priority is clear: the reinforcement-learning algorithm must deliver high accuracy in tracking the reference—voltage, current, or power—throughout irradiance and load changes. Here is what I expect: • A modular Simulink file where the PV array, my custom boost converter, the single-phase inverter, the LCL or LC filter, and the grid interface are clearly separated so I can swap devices in or out. • A PPO training script (MATLAB RL Toolbox or compatible Python interface) that learns directly on the Simulink environment and saves ...

...is faster in the moment—and store that image alongside the delivery record. Once the parcel is handed over, a simple “Delivery Complete” tap finalises the job, records a timestamp, and moves the task to the completed list in the back office. I will provide the Tally database structure and sample invoice layouts. Your role is to build: • A driver-facing Android app using native Android (Kotlin / Java) or a robust cross-platform framework that still allows full access to device GPS and camera APIs. • An admin web panel (or Android tablet view) where I can push routes, see live vehicle locations on a map, resend customer notifications, and export completion summaries. • Secure REST or GraphQL endpoints so the app and panel stay in sync even wit...

...coordination. Users must be able to create and view patient records, assign or accept caregiving tasks, exchange status updates in real time, and track outcomes. All data must move securely between the web portal, the two mobile apps, and the database layer without duplication or loss. Technical expectations I am open to modern frameworks—React or Vue for the web front end, Swift/Objective-C and Kotlin/Java (or a cross-platform solution such as Flutter or React Native) for the mobile layer, and a scalable REST or GraphQL API behind it. Containerised deployment on AWS, Azure, or GCP with automated CI/CD, monitoring, and routine backups is essential so maintenance stays predictable. Key deliverables • Production-ready web application (health & social care focus...

...growth. The raw clips are already energetic; what I’m missing is a clean, professional polish—crisp cuts, colour-balanced frames, and smooth transitions or motion effects that enhance the pace without feeling gimmicky. Here’s what I’m counting on you to handle: • Take the footage I’ll provide through Google Drive and craft short (sub-60 second) 1080 × 1920 videos, fully optimised for the Reels algorithm. • Apply tasteful transitions and light effects only where they lift the momentum of the running scenes; no need for flashy overlays or heavy text. • Deliver both the ready-to-upload MP4s and the editable project files (Premiere Pro, Final Cut, or DaVinci Resolve—whichever you prefer). Acceptance criteria: • Visua...

...flight-path stroke can glide over the peak. • Of the three elements (roof, scan line, path), the aerial roof must be most visually dominant, because that is the service I sell. • Overall styling leans modern rather than purely technical; keep the forms minimal, balanced and easily legible at small sizes.

...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...

...responsiveness. Connection stability, automatic reconnection, and graceful handling of Bluetooth state changes are essential because the app will often run in the background. Deliverables • A self-contained React Native module (TypeScript or modern JS) that wraps all BLE operations and exports easy-to-use hooks or callbacks. • Native bridge code where needed (Swift/Objective-C for iOS, Kotlin/Java for Android) so the same JavaScript API works on both platforms. • Clear documentation and a short demo screen that prints live weight values, connection status, and battery level if the scale exposes it. • Unit tests or a simple test script proving that the module reconnects automatically after signal loss and remains within ±200 ms latency for updates...

... current quiz scores, and weekly streaks; teachers or parents should be able to glance at the same data on a lightweight dashboard. Think Firebase or an equally quick cloud back-end for syncing, but I’m open to the stack you prefer as long as the data stays secure and the UI remains snappy on entry-level Android phones. Core deliverables (acceptance criteria): • Android APK + source (Kotlin or Java) compiled against the latest stable SDK • Audio-first lesson player with play / pause / seek and buffered streaming for low-bandwidth connections • Gesture-friendly interactive activities (drag-and-drop, tap to match) that tie directly to the audio content • Quiz engine supporting multiple-choice, fill-in-the-blank, and picture-based prompts, with real-...

I need a small tool that can look at live or historical rounds from a typical Crash-style game and predict whether the next round will land on the green or red colour. I am not tied to any particular language or framework, so feel free to choose whatever stack lets you tap the data source quickly and build an algorithm that improves as more rounds are observed. All I want on my side is a simple interface—command-line, lightweight webpage, or even a desktop window—where I see the last few rounds, your predicted colour for the upcoming one, and a confidence score. If you prefer, the prediction can simply be printed to the console; slick visuals are not a priority, accuracy and speed are. Please include: • A brief description of the logic or model you use (stat...

...it has to be, but polished enough to feel professional. Core workflow • Patients open the app, review each doctor’s profile (photo, specialty, brief bio, available hours). • They pick an open slot and confirm the booking. • A push notification reminds them as the appointment approaches. That’s the heart of it. I am open to your preferred stack, yet an Android-native build in Kotlin or Java via Android Studio will likely keep things straightforward. If you already have experience wiring notifications through Firebase Cloud Messaging—or a comparable service—please mention it. Deliverables 1. Full Android source code with clear project structure. 2. Debuggable APK for testing and a signed release build. 3. Short hand-off guide ...

The work will be considered complete once the source compiles without errors, the main dashboard successfully pulls a user’s channel analytics, and the basic upload/schedule fu...

...YouTube Short. The vision is simple: keep it vertical, under sixty seconds, and packed with momentum. I want the absolute key moments front and center—no fluff—stitched together with quick, punchy cuts that hold viewers to the very last frame. Also the first 20 seconds where players are walking towards me and using buffs must be added Text overlays are a must. Think dynamic wording like “Elden Ring boss fights hit different with the squad” popping up right when the hype peaks. Feel free to match the font and animation style to typical gaming-short aesthetics, as long as it never distracts from the action. A light pass of sound design, snappy zooms or speed-ramping where it suits the footage, and a final export in 1080×1920 ready for immediate u...

Scope • Diagnose and fix existing errors in the REST layer, services, or related model classes. • Add clean, well-documented GET and POST endpoints so devices can reliably push data and consumers can pull it back. • Ensure responses follow our current JSON schema and return the correct HTTP status codes. • Provide concise unit or integration tests that demonstrate each fix or new endpoint working end-to-end. Acceptance criteria A pu...

I’m rolling out a new feature that touches both ends of our stack. On the backend we run Java 21 with Spring Boot micro-services, alongside a small Node.js/Python layer that exchanges events through Kafka. The frontend is split between an older Angular module and a newer React interface. The job is to design and code the complete feature, wiring it cleanly into every affected service and UI surface. You will: • Extend (or create) the relevant Spring Boot endpoints, making sure they publish and consume the right Kafka topics. • Update the Angular dashboard and the React SPA so the user experience is seamless across both frameworks. • Keep code idiomatic, unit-tested, and pushed to our Git repo via pull requests. Acceptance criteria • All API tests p...

...Suite, all while keeping the tone approachable but expert. For YouTube, I’m aiming for story-driven pieces that take followers inside my personal trading experiences: real trades, lessons from wins and losses, and the thinking that happens between entry and exit. Each upload needs clean cuts, clear charts on screen, subtle motion graphics, keyword-rich titles, descriptions and tags to help the algorithm surface the videos. Deliverables • Weekly content calendar aligning Instagram reels (5 per week, 60–90 s each) with market events. • Two 8–12 minute YouTube videos per month built from my raw footage or Zoom recordings. • Custom thumbnails for every asset. • Monthly performance snapshot covering follower growth, reach, watch time and...

I’m creating an online store for cosmetic products and want the codebase to feel as professional as anything you would ship to production. The backend must be written in Java with Spring Boot, exposed through well-structured REST endpoints, and persist data in MySQL. On the client side I only need a clean, responsive interface built with plain HTML, CSS and vanilla JavaScript—no heavy frameworks—so that the focus stays on clear architecture rather than flashy UI libraries. Core features I expect: • Role-based authentication for Admin and Customer accounts, supporting registration, login and logout with secure password storage. • Admin dashboards to add, edit and retire products, plus view basic order information. • Customer-facing catalogue with...

I’m expanding several engineering teams for top-tier MNCs and rapidly scaling tech start-ups and need skilled people who can jump in right away. The first seats I must fill are: • Software Developers who are fluent in React, Node, and/or Java.

...authentication, real-time data synchronisation to our backend, and reliable push notifications. The server side is already live; you’ll consume our REST/JSON endpoints and make the tablet experience fully in step with the web version. Because this is a contract role I need someone who already has at least five years of hands-on APK work under Linux—comfortable with Android Studio, the Android SDK, Kotlin/Java, Git, and typical CI pipelines. You should be able to stand up a clean architecture, guide me on best practices for tablet UI/UX, and hand over production-ready code. Deliverables I’ll sign off on: • Compiled release-grade APK ready for Play Console internal testing • Complete, clean source code in a Git repo with build instructions that wor...

...quick-access buttons to the most-used modules. Smooth pull-to-refresh, badge counts, and Firebase push integration should mimic the existing behaviour exactly. 2. Profile – Students and staff need a tabbed layout that presents personal details, attendance records, and grades/performance, all pulled from our current REST endpoints. Data caching, photo upload, and simple edit forms already exist in Java and must be replicated in Dart without losing validation rules. 3. School Contacts & Calendar – For this first sprint I only need the staff directory portion live. Search, role filtering, click-to-call, and email links should work out of the box. The calendar view may stay read-only for now; it simply has to render the same event feed we already expose in JSON....

I’m developing a concept of Ring, and I need a skilled industrial designer to turn the idea into a production-ready product. Your role will start with refining the overall form factor so it feels comfortable, visually appealing, and clearly communicates its tech-forward nature.

Deliverables will include: • Concept sketches and mood boards that explore styling directions • Finalized 3D CAD (STEP + native files) with assembly hierarchy • Rendered visuals for investor decks and marketing teasers • CMF(Color, material, finishing) I’ll ...

I’ve got a single Ring doorbell recording—roughly 5-15 minutes long—and I need the soundtrack isolated and polished so every spoken word comes through clearly. The main objective is speech clarity; right now wind noise washes out key phrases and makes the conversation hard to follow. Here’s the flow I have in mind: you pull the audio from the video, run a careful pass to strip out that wind interference, then balance, EQ, and compress as needed so voices sound natural without introducing artifacts. Feel free to lean on iZotope RX, Adobe Audition, Audacity plug-ins, or any tools you trust, as long as the final file is clean, levelled, and ready for review. Deliverable • One high-quality WAV or MP3 containing the cleaned audio, with wind noise effectiv...

...Android-only mobile app from concept to Google Play release. The exact domain is still flexible—e-commerce, social networking, productivity, or another category that makes strategic sense—so I’m looking for a developer who can help me shape the idea as well as code it.

Depending on the agreed use-case, the build may include fundamentals such as messaging, user profiles, a news feed, or any other feature set that fits the solution. Code should be written in Kotlin or modern Java within Android Studio, follow current Material Design guidelines, and be structured for easy maintenance and future feature expansion. Deliverables • Fully-tested APK and complete source code • Brief technical documentation outlining architecture, key libraries, and build steps • One walkthrough session to hand over the project and address ques...

...and the practicality of everyday utilities. Think of it as one cohesive product where users can play, chat, share photos, connect with friends, and still reach for built-in tools that make daily life easier. Here is what I already know I need: in-app messaging, seamless photo sharing, and a robust friend-connection system. Because we’re targeting Android only, you’re free to lean into Kotlin or Java and make the most of Google-first services—Firebase for real-time chat and push, Play Games Services for leaderboards or achievements, and any modern Android Jetpack libraries that speed development while keeping the codebase clean. I’ll handle concept art and copy; you’ll take charge of architecture, clean UI/UX, feature implementation, and release-rea...

I need a (formerly Integromat) scenario that pulls fresh leads from three affiliate sources—TrackBox, GetLinked and Dr Mailer—masks every phone number, then posts the sanitized records into my self-hosted CRM through its API with auto-login tokens. The same workflow must also append a Squaretalk click-to-dial link so that, once the lead lands in the CRM, an agent can ring the prospect with a single click. All steps have to run in near real-time, handle errors gracefully and log every transaction for audit purposes. Deliverables • A blueprint with Webhooks, parsing modules, a masking function (e.g., keep first two and last two digits, replace the rest with ✱) and an authenticated POST to the CRM API. • Squaretalk integration that converts the masked nu...

We are looking for an experienced Amazon listing expert to create and optimize a high-converting product listing.
