I want to commission a full-featured Android application dedicated to organising eSport scrimmages and small-scale tournaments. My budget for the entire build is approximately US $1,000, which I will release in clearly defined milestones (prototype, beta, final release, and demo video). Core scope The app has to let players create and manage teams, schedule matches effortlessly, and keep ongoing statistics so organisers can review past performances. Because most users will expect a quick sign-up flow, social-media login options (Google, Facebook, Twitter) need to be baked in from the start. I also need a lightweight in-app payment gateway so teams can pay entry fees or unlock premium brackets without leaving the platform. Deliverables • Production-ready Android APK and source code (Kotlin or Java). • An admin panel (web or in-app) where I can approve teams, edit match times, and view aggregated stats. • A short demo video or live walkthrough showcasing team creation, scheduling, stat tracking, social login, and a test payment flow. • Clean, well-commented code and a concise setup guide so I can compile and publish future updates myself. Acceptance criteria 1. New users can register via at least two social networks and land on a functional dashboard in under a minute. 2. Team captains can invite players, create a match request, and have it automatically appear in both teams’ calendars. 3. Match data (scores, player K/D, etc.) persists locally and on the server, updating leaderboards in real time. 4. Test payments run smoothly through the chosen gateway’s sandbox and generate a receipt inside the app. 5. The demo video shows every feature above in action on a physical Android device, not an emulator. Feel free to propose the stack, server architecture, or any third-party APIs that can speed up development while keeping costs in line with the stated budget.
