Asiakkaamme antoivat 243,081 arvostelussa keskimääräisen arvosanan Java Developers 4.9 / 5 tähteä.I’m building a new mobile application and I need a robust Java Spring Boot backend to power it. The core services you’ll create must cover: • User authentication and management with full multi-factor authentication (MFA) and support for future multi-party authentication flows. • A streamlined customer-onboarding journey that begins with registration and ends with a verified, fully profiled user record. • Reliable data storage and retrieval using a relational engine—MySQL or PostgreSQL, whichever you are most comfortable optimising. RESTful APIs should be documented with Swagger/OpenAPI, secured with JWT or a similarly strong token strategy, and thoroughly unit- and integration-tested. I’ll provide the mobile team’s contract-first API s...
I need a warm, intuitive Android-only mobile app that lets users enjoy seamless conversations with a “friendly chat partner.” The core of the build is real-time communication on three levels: • Text chat • Voice chat • Video chat Please code natively for Android (Java or Kotlin via Android Studio) so the experience feels fast and integrated. I’m happy to rely on proven back-end services such as Firebase for authentication and real-time text, and WebRTC or a comparable library for voice and video—feel free to suggest the stack you’re most comfortable with. Key goals – Clean, welcoming UI that encourages users to start chatting within seconds – Reliable connection handling to keep calls and messages stable on spotty netwo...

I’m building a small showcase app for a school contest and need a polished Android solution that makes printed text friendlier for students with dyslexia. The flow is straightforward: the user opens the camera, points it at a page, and the app instantly recognises the words (OCR). As soon as the text is captured, each word is spoken aloud in sequence while that same word is highlighted on-screen in real time. The result should feel like a karaoke-style guide that lets the reader follow along word by word without losing their place. Must-have fundamentals • Android only — Kotlin or Java is fine, as long as it runs smoothly on common mid-range phones. • Real-time OCR (Google ML Kit, Tesseract, or any on-device library you prefer) with no dependency on an active int...
I need an end-to-end web application written in pure Go, backed by a MySQL database. The core focus is clean, idiomatic code that can be compiled and deployed on a standard Linux server without fuss. You’re free to structure the project with popular Go web frameworks such as Gin, Echo, or Fiber, as long as the final build remains lightweight and easy to maintain. I will supply server access and a blank MySQL instance; you take it from there—designing the schema, wiring up the handlers, and exposing routes that follow REST principles. Code quality, straightforward error handling, and secure interaction with the database are priorities. If you prefer containerisation, feel welcome to include a Dockerfile so the whole stack can spin up locally with a single command. Deliverables...

I run a Java-based restaurant management application and need it to talk seamlessly to both Swiggy and Zomato so that staff never have to re-enter data in multiple dashboards. The scope is straightforward: connect to each partner API, pull menus, push updates, receive orders instantly, and track every delivery milestone without manual refreshes. Real-time event handling (webhooks or long-polling, whichever the platforms allow) is essential so that kitchen screens and POS reports stay in sync second-by-second. Please deliver: • Menu synchronisation: create, update and deactivate items and modifiers from my app and reflect those changes on Swiggy and Zomato. • Order management: ingest new orders automatically, send accept/cancel actions, print kitchen tickets, and post order stat...

I need a straightforward Android application that lets my customers send money to me by bank transfer. After signing up or logging in with the classic username-and-password flow, a user should be able to choose an amount, see (or pre-fill) my banking details, and push the payment through an integrated bank-transfer API. Security is critical, so the credential flow must be encrypted end-to-end and the transfer requests signed or otherwise verified to prevent tampering. A lightweight backend—REST or Firebase Cloud Functions is fine—can manage authentication, session tokens, and payment-status webhooks. Please deliver: • Full Android Studio project (Java or Kotlin) • Secure username/password authentication flow • Bank-transfer API integration with success/...

I’m ready to move beyond notebooks and actually ship models, but I’d like to do it the right way, step by step, with an expert by my side. My stack of choice is Python, and we’ll be working on Google Cloud. The part I’m most eager to master is model serving and building production-grade APIs, though I still want you to frame everything in an end-to-end workflow so the pieces fit together. Here’s how I picture our work together: • Pair-programming sessions where we containerise a trained model, push it to Google Cloud (e.g., Cloud Run or Vertex AI), and expose it through a REST or gRPC endpoint. • Walk-through of best practices for versioning, environment management, and automated CI/CD so each new model can be rolled out with minimal friction. ...

I’ve just finished deploying a new Android mobile application and everything appeared to go smoothly—until I tried to launch it. Right after installation the app attempts to talk to the backend and immediately throws a server error. The APK itself installs without complaint; the trouble starts only once the first request is sent. I need someone to dive in, locate the root cause on the server side, and implement a clean fix so the app can connect reliably every time. Access to the server, source code, and crash logs is ready for you as soon as we agree to move forward. Please bring experience with common Android back-end stacks (Node, PHP, Java, or similar) and a methodical debugging approach. Once resolved, I’ll confirm the build installs and runs error-free on multiple ...

The project is to build a Python-based bot that trades equities on NYSE, NASDAQ, and AMEX. It must run end-to-end without manual intervention: gathering live market data, analysing it in real time, placing orders, and continuously enforcing risk limits. Core functionality • Automated trade execution driven by a configurable strategy engine • Real-time market analysis with fast data ingestion (websocket or streaming API) • Built-in risk management: position sizing, max draw-down and stop-loss rules Technical notes Python is mandatory; common libraries such as pandas, NumPy, TA-Lib, and asyncio are expected. The code should be clean, modular, and ready to plug into broker APIs like Interactive Brokers, Alpaca, or Tradier. A lightweight front-end (CLI or simple dashbo...
My Android Studio Java app is still targeting API 34 and I need it fully brought up to API 36. Alongside the version bump, I want the codebase tightened so it runs more efficiently and the overall look refreshed with a modern theme. Scope • Update Gradle files, libraries and any deprecated calls so the project compiles cleanly against API 36, including new permission or foreground-service requirements. • Profile and refactor hotspots to shave unnecessary CPU / memory use and eliminate obvious jank. • Re-skin the app with a contemporary Material-based theme—colours, typography and styles—while preserving existing layouts and behaviours. Upgrade all the dependencies used in the project. Acceptance The upgraded project must build without warnings on the l...
I’m kicking off the development of a brand-new enterprise application and I want it built with the latest version of Angular from day one. The project starts with a clean slate, so you’ll have full control over the architecture, folder structure, and tooling choices. Two capabilities must be rock-solid: • User authentication – Single-sign-on, role-based access control, token refresh, and secure session handling are required. • Integration with other systems – REST and/or GraphQL endpoints, webhooks, and potential third-party SDKs will need to be wired in so data can flow smoothly across our existing platforms. Beyond those essentials, code quality, unit/integration test coverage, and straightforward CI/CD pipelines (GitHub Actions or similar) are expe...
Android CameraX & API Integration (We have 80% of the code logic ready - No R&D needed) We are looking for an experienced Android Developer to build a technical prototype (MVP) focused on real-time image processing for a Huawei P10 device. IMPORTANT: We are not reinventing the wheel. We have already completed the research phase. We will provide you with: 1. The Official SDKs and Documentation needed for the project. 2. Reference Code (80% of the logic): We have identified specific open-source samples (Google Samples) that already handle the image capture and API request logic. Your job is NOT research.

I’m building and maintaining a series of backend services and I need an experienced Python developer who feels at home in FastAPI. The day-to-day work centres on designing clean, scalable REST endpoints, wiring them to a PostgreSQL database, and keeping the Dockerised environment tidy for smooth deployments. Most of the upcoming tasks involve integrating external providers: think payment gateways for transaction flow and AI/ML services that power in-app intelligence. Beyond those, you’ll help craft automation scripts, refine existing business logic, and keep an eye on performance as traffic grows. Here is what a typical assignment looks like: • create or extend a FastAPI micro-service • expose secure endpoints, including user auth where required • conne...
I need a small Android proof-of-concept that launches the UIDAI FaceRD app via an explicit Intent, waits for the capture flow to finish, then receives the returned PID XML (biometric) data and renders it on-screen or writes it to logcat. Here is exactly what I expect: • An Android Studio project (Java or Kotlin) that targets any current SDK version compatible with FaceRD. • A signed, installable APK so I can test immediately. • On tap of a single button the app should: 1. Invoke with the correct action, extras and flags. 2. Handle the result in onActivityResult / ActivityResult API, extract the PID block, and show it clearly (raw XML is fine for the demo). Once I confirm the APK works, I will need the full, clean source code together with a sho...
I need a developer who can build a clean, stable Android application that lets users sit for fully-timed mock exams. The core of the project is the timer: each session must start, pause, resume, and submit automatically when time runs out, mirroring a real-world exam environment. For this first release I am only targeting Android, so please use a modern, well-supported tech stack (Kotlin or latest Java with Android Jetpack components). The UI should be lightweight and responsive, leaving room for future additions such as a question bank or analytics—but those extras are not in scope right now. Acceptance criteria • Home screen listing available mock tests • Start screen that clearly shows remaining time once the test begins • Automatic submission when the c...
Our theme’s JavaScript that decides whether the “Add to Cart” button or an alternate, price-based button shows is misbehaving. The switch fails specifically when a customer moves between variants: the button simply doesn’t refresh, even though the price does. I need you to step through the existing variant-handling code, pinpoint the root cause, and rebuild the logic so it works every time—without resorting to fragile work-arounds. Please keep the implementation clean, readable, and in line with Shopify best practices (Liquid, , Section rendering, DOM-ready events, etc.). Deliverable • A fully tested, production-ready fix that updates the price-based button correctly whenever a shopper selects a different variant, with no regressions to availabili...

I urgently need a seasoned Android engineer to take a brand-new idea from concept through to a fully working application. The exact feature set is still open for discussion, but whatever we build must run smoothly on both the latest devices and older phones and tablets without breaking UI or functionality. You will handle architecture, coding, testing, and deployment to Google Play, providing me with the full source code and a signed APK at each milestone so I can track progress. Expect to optimise for performance, follow modern Material guidelines, and implement solid backward-compatibility strategies—whether that means leveraging AndroidX, shrinking the APK with ProGuard/R8, or tailoring layouts with resource qualifiers. Clear, well-commented Kotlin or Java, Git-based version...
I am looking for a developer who can turn my idea for an Android-only social networking app into a polished, launch-ready product. The core experience should let users register quickly, build a profile, connect with others, share posts (text, photo, or video), react or comment, and chat in real time. A clean Material design, smooth performance on recent Android versions, and push notifications are essential. I plan to monetise later, so the codebase needs to be structured for easy integration of ads or in-app purchases. If you are comfortable working natively in Kotlin or Java and have handled cloud back ends such as Firebase, Supabase, or a comparable stack, your expertise is exactly what I need. Security best practices, scalable database design, and simple analytics hooks all matter to ...

I want to launch a non-custodial crypto wallet that covers the essentials from day one. Users must be able to send and receive coins or tokens, browse a complete transaction history, and restore access at any time through a secure backup flow (seed phrase or encrypted file). The first release targets Android and a browser-based version. Feel free to use Kotlin, Flutter, React Native, or similar for mobile, and React/ (or comparable) for the web client, so long as the codebase is clean and well-documented. Security should follow a solid “standard” approach: client-side key generation, AES-256 encrypted private keys, optional PIN/biometric unlock, HTTPS everywhere, and no server-side custody. Compliance with common audits or libraries (e.g., WalletConnect, ) is welcome but not...

I need an Android-only time management app whose core purpose is to keep users on schedule through smart notifications and reminders. The flow is simple: a user sets a task, defines a deadline or ideal start time, and the app nudges them at just the right moments. You are free to choose the framework (native Kotlin/Java or a cross-platform option that still compiles cleanly for Android) as long as the final build is stable, responsive, and Play-Store-ready. I’ll want both an installable APK and full, well-commented source so I can iterate later—potentially adding task scheduling or full time-tracking modules down the road. Key expectations • Clean, modern UI that feels intuitive on current Android versions • Reliable foreground and background notification ha...
I want a clean, lightweight Android application that my field sales team can open, log in with their company email and password, and capture secondary-sales orders on the spot. Two roles matter to me: • Salesman – enters demand, adjusts MRP-based discounts, and submits the order. • Manager – reviews or edits what the salesman submitted and can pull quick reports. The core flow is simple: after login the salesman selects the customer, adds products with quantities, sees the auto-calculated total, applies any discount by percentage or value, and taps “Generate Order”. The app must immediately create a branded PDF containing all line items, MRP, discounts, net values, date/time, and the salesman’s details. That PDF should save locally and be shareab...
I’m ready to turn my idea into a fully-functional Android application and need a developer who can guide the process from concept to Google Play release. At this stage I have the core concept and a handful of rough sketches; what I need now is help refining the user flow, designing an intuitive interface, building the backend logic, and packaging everything into a clean, well-tested APK. You’ll be working exclusively for the Android platform, so familiarity with current SDK versions, Kotlin or Java, Android Studio, and the play-store submission process is essential. If you can also advise on best-practice architecture (MVVM, Clean Architecture, Jetpack components) and integrate common services such as Firebase or in-app billing, that’s a plus. Please let me know: ...

For each session I will need: • well-structured slide deck or whiteboard notes • the live notebook / script you write during class • a short, working demo project or e...
I’m ready to launch a proprietary AI-driven builder inspired by Lovable and Base44. The vision is a web-based platform where non-technical users can assemble complex assets in minutes while the system quietly orchestrates the heavy lifting—model selection, training, and deployment—behind the scenes. You’ll guide the entire build: architect the cloud infrastructure, code the core engine, design an intuitive front-end, and wire everything together with robust APIs. Think drag-and-drop creation, reusable templates, realtime previews, and seamless connections to popular third-party tools so that users can publish or integrate their results without touching code. On the AI side I’m open to the mix you feel best suits the goal—classical machine-learning pip...
