Over mij
Flutter & Firebase developer with 4+ years building production-ready iOS and Android apps for clients worldwide.
I specialize in turning ideas into real, working apps with clean code, smooth UI, and zero guesswork on delivery.
What I bring to every project:
✅ Firebase Auth, Firestore & cloud storage
✅ GPT-4 AI chat integration
✅ Subscription paywalls (StoreKit/RevenueCat)
✅ App Store & Play Store submission
I don't just write code I solve problems. Every app I deliver is tested, documented, and built to scale.
Let's build something great.
