About Me

Production-ready doesn't mean it just works in the demo.

I'm a full-time freelance Flutter developer who helps agencies and founders turn ideas into live App Store and Play Store products, without the hand-holding, missed deadlines, or messy code. Over 2+ years and 8+ shipped apps , I've built everything from tightly-scoped startup MVPs to complex multi-role platforms, AI-powered features, Firebase backends, and secure payment flows.

What sets me apart is what happens after launch. I build on clean architecture and maintainable code, so your app works as well with 100,000 users as it does with 100, and adding your next feature is fast and painless, not a rewrite. Clear communication, honest estimates, and apps that ship on time. That's the whole deal.
