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...

I’m kicking off a project to build a well-structured spreadsheet of companies active in Oil & gas, Engineering, Construction, Mining, Industrial Services and Energy. Your first assignment will be a small, paid pilot so we can confirm approach and quality before scaling up to a larger roll-out. You will search publicly available sources, pinpoint relevant firms, and capture the data points defined in the attached instructions. Accuracy, consistency and clear source attribution are essential because the sheet will feed directly into our internal analytics workflow. Deliverables for the pilot • A clean spreadsheet populated to the template provided • One source link (minimum) for every data field captured • Notes on any gaps or ambiguous ...

...smoothly over the long term. Core feature focus The applications revolve around patient management and caregiver 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...

...full ownership of our server-side codebase and keep it evolving over 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. &bul...

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 co...

...plain terms. I already have the UI skeleton; what I need is the core engine that discovers the Acacia device, negotiates the GATT services/characteristics it uses, then streams weight data with millisecond-level 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, connect...

...awards instant feedback, and records the result. A simple progress-tracking module is essential: learners must see how many lessons they have completed, 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-a...

...is pure automation: eliminating manual data entry while keeping the standard Flexcube flow intact. Here is what matters most: • The service that supplies the data is already live and documented—your job is to consume it, map its JSON response to the correct Flexcube fields, and invoke the page in create mode. • Only personal information (name, date of birth, ID numbers, etc.) has to be filled. Basic validation—presence checks and simple format rules—is sufficient; anything more can stay out of scope for now. • The end result should feel native: once the API call succeeds, the user sees the customer screen with every mapped field in place and can immediately continue the usual onboarding process. Deliverables I expect: 1. Integra...

Here is what I expect: • Add or correct contentDescription attributes, accessibility labels and hints so that controls are spoken in a logical order. • Ensure state changes—errors, success messages, toggles—are conveyed via accessibility events without relying on visual cues alone. • Keep visual layout untouched; all work should sit cleanly in the XML and Kotlin/Java layers. • Provide a short video or emulator capture showing TalkBack reading through a typical form flow, plus the updated source files or a merge request. If you regularly validate with TalkBack, Accessibility Scanner or Espresso accessibility tests, this will be a straightforward engagement. Let me know the Android versions you usually test aga...

I maintain a Java-based backend that exposes a small REST interface for sensor and other device data. A few legacy issues are breaking current GET and POST calls and I also need several new endpoints added. Each confirmed bug you resolve is paid at ₹1,200, and the same rate applies if you prefer to log time hourly instead. 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 c...

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...

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 catalog...

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. If you can architect front-end components in React, build robust APIs with Node, or craft enterprise-grade services in Java, you’re already on my shortlist. • Data Analysts & Data Engineers able to turn raw data into clean, actionable insights. Solid SQL skills are essential, and if you have experience with Python, Spark, or comparable tooling, that will be an added advantage. • UI/UX Designers who can translate complex product ideas into polished, user-centric interfaces, balanci...

...existing web application, so rock-solid integration is everything. Here’s the core of what you’ll be doing: the app is brand new (nothing to refactor) and must ship with secure user 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 c...

...of today’s stats, and provide 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...

...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. Here’s what I need from you: • Discovery & wireframing sessions to refine the core feature set • Clean, maintainable Kotlin or Java code that follows Android best practices • A modern UI built with Material Design components • Integration of essential services such as authentication, push notifications, analytics, and in-app purchases when relevant • End-to-end testing, including unit tests and UI tests, with clear test reports • Assistance with ...

This project centres on building a native Android application from the ground up. The exact domain is still open—whether the final product supports e-commerce, social networking, education, or another category will be decided once we refine the concept together. Key functionality is equally flexible. 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 archite...

...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-ready optimisation. Reusable, well-documented code is important, as I want the flexibility to add more mini-games or utilities later. Deliverables • Complete Android Studio project with clear package structure • Signed, ready-to-upload APK/AAB ...
