The job goes beyond simply spinning up the software: once the core platform is running, I want the Payment systems, Member management, and Marketplace modules fully enabled, tested, and ready for real-world use. Please secure the installation, connect any required dependencies (Java, PostgreSQL, reverse proxy, HTTPS, mail service, etc.), and walk me through basic administrative tasks so I can manage users and currencies on my own. SSH access to a fresh VPS can be provided immediately.

    I’m planning to release a focused utility app for Android and need a developer who can take it from concept to a polished, store-ready build. Because the app will live solely on Android, you should feel comfortable working with the latest Android SDK, Kotlin or Java (your preference), and Google Play Store compliance requirements. Here’s what I’m expecting: • Fully functional APK that runs smoothly across current Android versions • Clean, well-commented source code pushed to a private Git repository • Brief setup / build documentation so I can reproduce the release on my end If you’ve shipped Android tools before—battery savers, file managers, system widgets, or similar—the project will feel familiar.

What you’ll hand back: • One rendered video, ready to upload, matching the reference style • All project or editable files in case tweaks are needed The budget is fixed at ₹200 per video, so this suits editors who want steady, simple work rather than a high-end production challenge. If you’ve done similar slide-style edits, send a link or two; otherwise a quick sample cut from any past project is enough for me to gauge fit.

The role is very straightforward: each day you’ll take text data I provide or locate online, copy it accurately, and slot it into either Microsoft Excel or Google Sheets depending on the specific file I share.
