I’m building the first-cut version of a lightweight demand-supply marketplace focused on Android. Users will come in, register quickly with phone number verification only, choose Hindi or English, and post what they need or what they can supply—covering both product and service categories. All open posts should appear in a public feed where anyone can tap to call or jump straight into WhatsApp with the poster. Core flow • Splash / onboarding → phone OTP login • Simple two-step form to create a demand or supply (category, location, brief description, optional photo) • Public list with filters by category and city • One-tap Call or WhatsApp actions Admin workspace (web or in-app is fine) must let me: • Approve or reject new posts before they go live • Edit user posts for clarity or compliance • Delete anything that violates policy General notes – Clean, minimal UI that loads fast on lower-end devices – Text strings externalised so I can maintain full Hindi/English support – Scalable backend (Firebase, Supabase, or your proven stack) ready for future iOS rollout – Source code, brief technical doc, and a hand-off walkthrough are part of the hand-over Please share two or three similar apps you have shipped, the core tech stack you propose, and how many weeks you need for the MVP. Looking forward to collaborating!
