About this gig

Looking for a developer who can turn a clear idea into a working app, not just a prototype that looks good in a demo? That is what I focus on.


I build cross-platform mobile apps in FlutterFlow and Flutter, with Firebase or Supabase handling authentication, databases, and storage. When the visual builder reaches its limit, I write custom code (Dart, SQL, API calls) to get the exact behavior the app needs.


What I can set up for you: FlutterFlow or Flutter app design and development, Firebase or Supabase backend with auth, database, storage and cloud functions, subscriptions and in-app payments with RevenueCat or Stripe, admin dashboards and role based access, API and AI feature integration, and App Store or Google Play submission support.


Every build is checked against store review guidelines, tested for load speed, and structured so it holds up once real users start using it.


Send me your idea, wireframes, or an existing app that needs fixes, and I will tell you exactly how I would approach it before you order.

I build mobile apps that work well from day one and hold up as they grow. My focus is FlutterFlow, Flutter, Firebase, and Supabase, with custom code added wherever the builder needs to go further. I set up subscriptions with RevenueCat or Stripe, build admin dashboards, and add AI features where they help. I also design and build the websites that sit next to these apps, so the product feels complete from end to end. I care about apps that pass store review, load fast, and hold up once real users show up. Bring me a clear idea or an app that needs fixing, and I will take it from there.
