I suggest using the first milestone to turn the confidential concept into a build-ready MVP foundation. I work with Flutter/Dart, REST integrations, authentication, databases, secure backends, and AI/API automation. For ₹35,000 fixed, I will: 1) review the detailed requirements under confidentiality; 2) define the MVP scope and user flows; 3) design the Flutter + Firebase/Supabase architecture, including secure API-key handling; 4) create the project foundation with authentication and one representative end-to-end flow; 5) provide a backlog, delivery estimate, and source-code handover. Scope: up to 16 hours over 5–7 working days. It excludes the complete production MVP, store approval, subscriptions, and open-ended support. A separate fixed quote can follow once the specification is validated. Which feature is the core paid-user flow? Do you already have API providers and UI designs selected?

Happy to work under NDA before you share the concept, so that is not a blocker. One thing worth deciding early, since it is expensive to reverse: FlutterFlow is excellent for reaching an MVP fast, but its generated project is where teams get stuck later. I build so custom logic lives in custom functions and actions rather than being trapped in the visual editor, and I hand over the exported Flutter project as well as the FlutterFlow one. That way, if the product succeeds and you outgrow the tool, you continue in plain Flutter instead of rebuilding. The other early decision is the backend. Firebase gets you live fastest and suits most MVPs; Supabase suits you better if your data is genuinely relational. I will recommend once I see the concept rather than defaulting. Included: build, both iOS and Android from one codebase, store-ready builds, and source handover.
