    My Android application is already live, but a lingering bug keeps mis-displaying the user’s Name and Referral No. I need an experienced Android developer who can dive into the existing codebase, trace the root cause, and push a clean, well-documented fix to Git (or your preferred VCS). Scope of work • Review the current Kotlin/Java code (the project uses standard Android Studio tooling). • Identify why the Name and Referral No. are not updating or showing correctly. • Implement a solid fix, test it across the latest Android OS versions, and supply an APK or bundle for verification. • Leave concise inline comments so future maintenance is straightforward. Deliverables 1. Updated source code with the bug resolved. 2. A brief change-log summarising what was ...

    ...accessing camera, storage, or sensors; the app must never crash on denied permissions. • Keep UI components modular and reusable—Material Design guidelines are a must so the catalog, product detail, and checkout screens feel consistent and modern. • Implement secure token-based authentication and persist sessions locally without compromising user privacy. • Ship the full, well-documented Kotlin/Java source, a signed release APK, and a short README explaining build and deployment steps. This is primarily an E-commerce app, so flawless product browsing, smooth cart operations, and responsive checkout flow are non-negotiable.

    I want to turn a fresh idea into a polished desktop application I can sell and use to support my family. I’m starting from the ground up, so I need a developer who can guide me through the full lifecycle—defining a viable concept, choosing the best tech stack, coding, testing, and packaging the final installer. You’re free to work in a language you’re most comfortable with—whether that’s C#, Java, Python, Electron/JavaScript, or something comparable—as long as the result runs smoothly on Windows and can later be adapted for macOS or Linux if sales demand it. Robust error handling, an intuitive UI, and clean, well-commented code are must-haves so I can maintain or expand the product later. Deliverables • A brief proposal outlining tw...

The rest of the code base and gameplay loop stay exactly as they are; your work lives purely in the React UI layer and the sprite sheet you supply. Here is what I need you to do: • Design a cohesive pixel-art skin for the health and status bars, sized for 1080p but readable down to 720p. • Deliver the pixel sprites (PNG and source Aseprite/PSD) plus the accompanying React component that swaps the current SVG/CSS bar with the new artwork while preserving all existing props and data bindings. • Hand off any small helper functions or CSS tweaks necessary so th...

The call must automatically adapt to changing network conditions and recover gracefully from brief drops. WebRTC is my preferred technology stack, but if you can justify another approach with equal or better quality and device support, I’m open to it. Please leverage native Android (Kotlin/Java) rather than a cross-platform wrapper; I want full access to platform APIs, proper permission handling, and Material-compliant UI components.
