I already own the complete source code for a multivendor e-commerce solution—similar in flow to Amazon or Blinkit—purchased from CodeCanyon. The package includes the customer app, vendor app, admin panel and back-end; what I need now is a clean, production-ready deployment for both iOS and Android, with a few visual and functional tweaks to match my brand. Scope of work • Install and configure the back-end (API, database, admin panel) on my server and connect it to Firebase for push notifications. • Re-skin the mobile apps: logo, colour palette, splash screens, and app-store assets. • Update basic business logic—shipping zones, GST settings, and payment gateways (Razorpay + Cash on Delivery). • Build and sign release APK/AAB for Google Play and an IPA for TestFlight, ready for my developer accounts. • Hand over the modified source plus a short deployment guide so future updates are straightforward. Timeline Everything needs to be tested, signed and submitted for store review within one month of project start. Expectations from you When you reply, include links or screenshots of past multivendor, grocery or marketplace apps you have successfully set up. That portfolio piece is the key factor in my selection. Acceptance criteria The app must allow a new user to register, browse products, add to cart, complete checkout and receive order confirmation without errors on both iOS and Android; vendors should be able to log in, add products and see orders in real time; the admin panel must reflect all transactions accurately. If that matches your experience, I’m ready to get this rolling.
