I want to launch a straightforward B2B marketplace app on Android that connects two distinct customer types: • Type A suppliers create and post leads. • Type B buyers browse those leads according to their saved location and other preferences and, if interested, reach out instantly by phone or WhatsApp. Core flows – Mobile-number verification gates every new account. – Each profile stores at minimum the user’s Business Name, plus the usual contact details. – Once inside, users see a clean Leads list with search / filter, can open a lead for full details, and Type B can tap to call or message. Server side The backend should be built in PHP (Laravel or similar is fine) with a MySQL database. An accompanying web admin panel lets me: • approve or reject new sign-ups, • view, edit, or delete any lead, • suspend or reactivate users. Deliverables 1. Android APP 2. PHP backend and database schema. 3. Responsive admin panel UI. 4. Basic deployment guide and API documentation. I value clean architecture, clear naming, and the ability to scale modules later (e.g., adding industries or payment features). Let me know your preferred PHP framework, estimated timeline, and any similar apps you have shipped. Using AI is fine, but not vibe coded - You must know your code.
