I need a lean, revenue-focused Android application built within roughly 7–15 days. The core idea is a service-based app whose interface stays clean and lightweight while keeping launch and navigation times snappy. Key workflow • Dual-mode sign-in: users should be able to register or authenticate via Mobile OTP as well as Email; whichever is quicker for them must work out of the box. • After login, a straightforward dashboard should greet the user, showing basic stats or options I can later customise. • A payment module may be added once the first build is stable; I am open to card, wallet or bank flows, so please keep the architecture extensible. • The budget is tight but flexible—show me which features fit first, and we can scale cost per milestone if needed. Admin needs I will operate everything from a small web panel with only the essentials: 1. User management 2. Content management 3. Data analytics Tech comfort zone Kotlin or Java in Android Studio, Firebase for OTP/email auth, and any clean MVVM/MVI structure you prefer are all fine. If you have a faster or lighter stack, let me know. Deliverables • Signed APK + Play-ready bundle • Source code in a private Git repo • Admin panel (web or embedded) with the three controls above • Brief deployment guide and hand-off call There is plenty more work after this pilot release—ongoing feature sprints and maintenance for the right person. Let’s discuss a phased plan that keeps performance high without blowing the budget.
