...performance, a minimal learning curve for the user, and an interface that feels modern on all current Android devices are all essential. Because the budget is tight, I want to keep the feature set focused: basic registration/login, one-to-one chat, push-style updates so new messages appear without manual refresh, and a small settings screen. I’m open to the stack you prefer—Kotlin with Firebase, Java with WebSockets, or another lightweight solution—so long as the result is stable and easy to maintain. Deliverables • Signed APK (ready for testing) • Full source code with clear comments • Simple but polished UI/UX assets • Brief setup documentation for future builds I value clear communication and quick turnarounds. When you reply,...
I’m giving the in-game interface of my browser-based idle game a full visual makeover and want it to scream retro pixel-art. The underlying logic is finished; all I need now is an eye-catching reskin. You’ll work directly in the existing Java back end and React/HTML front end, refactoring only the visual layer—layouts, components, sprites, colours, fonts, animations—while keeping every hook, state and API call intact. The Sprites and the UI-Elements are already existing and was created by me. Here’s what I’m after: • A cohesive pixel-art look inspired by classic arcade screens—bold palettes, chunky fonts, sharp contrast. • Clean React components and CSS that make future tweaks painless (feel free to vibe-code small utility com...
...interface that looks clean, modern, and unmistakably premium—smooth animations, thoughtful spacing, and consistent typography are essential. • Integrate fundamental e-commerce features: searchable catalog, product variations, shopping cart, wish-list, multiple payment gateways, and push notifications for promotions and shipping updates. Technical expectations • Develop in Kotlin (preferred) or Java, following current Android best practices. • Use a scalable architecture (MVVM or similar), with clear separation of concerns and easy-to-maintain code. • Connect to my existing RESTful API; handle authentication, pagination, and error states gracefully. • Ensure compatibility with Android 8.0 (Oreo) and above. Design direction I already...
...experienced Android developer to turn my concept into a polished, production-ready app built natively for the latest Android SDK. I’ll provide the overall functionality goals during kickoff, but the visual direction must come entirely from a custom design created from scratch—no templates or off-the-shelf themes. Your process should cover UX wireframes, high-fidelity UI mock-ups, and the full Kotlin/Java codebase, all aligned with current Material Design guidelines while still feeling unique. Smooth performance, clean architecture, and well-commented code are essential because I plan to scale and maintain the app long-term. Deliverables: • Interactive Figma (or similar) design files • Compilable Android Studio project with source code • Signed re...
...single-page PDF ready for distribution. My design file shows exact font sizes, margins, headers, and footers, so the app must respect those specifications pixel-for-pixel. Dynamic text should auto-shrink only when a block overruns its allotted space; everything else should remain fixed. No images or tables need processing—pure text only. I’m open to your preferred stack (Python with PyPDF2/PDFPlumber, Java with PDFBox, or any robust alternative) as long as the final solution: • Runs on Windows 10+ without extra paid dependencies • Processes at least 200 pages in under two minutes on a standard laptop • Lets me update the template later without touching the core code (e.g., via an external JSON or simple GUI field map) • Outputs a perfectly...
I’m looking for an experienced ethical hacker who can also roll up their sleeves a...user stories and specs that I provide, translating them into secure, efficient software. Day-to-day you’ll be analysing requirements, recommending upgrades, collaborating with the rest of the dev team, and documenting everything—from flowcharts and user guides to the exact remediation steps you take. Routine maintenance and performance tuning are part of the remit as well. A solid command of Java and Python is essential, and you should feel at home in relational databases like MySQL, Oracle or SQL Server. If you’re detail-oriented, think critically under tight deadlines, and enjoy owning both the break-in and the fix, let’s talk about the next penetration target and ...
I’m ready to launch a clean, fast personal blog and need a developer who can take it from blank repo to live site. The stack can stay lightweight—HTML5, CSS3, and vanilla JavaScript on the front end, with PHP (or Java if you prefer) handling any server-side logic. We’ll work in VS Code so everything stays transparent and easy to review. Core requirement: a working comment section that lets readers leave, edit, and delete their own thoughts while protecting the site from spam. I’m open to adding extras such as social media hooks or a search bar later, but for this first milestone the focus is the blog itself and the comment workflow. Deliverables • Fully responsive blog template with home page, post page, and error page • Comment system (CRUD o...

I want to turn my cab-booking idea into a polished mobile product that runs smoothly on both iOS and Android. The core requirement is straightforward: riders must be able to book a cab from their phone, watch the driver approach in real time, and handle payment without ever leaving the app. Because the project targets both major platforms, I am open to native builds (Swift + Kotlin/Java) or a proven cross-platform stack such as Flutter or React Native—whichever delivers the best blend of performance and maintainability. Whichever route you recommend, I expect feature parity across devices. Key functions I need from day one include: • Secure user authentication • Real-time ride requests and status updates (push notifications) • Live location tracking on an ...
