I'm a full-stack mobile developer with 5 years of experience building production-grade apps for iOS and Android. I specialize in Flutter and React Native with Firebase as my primary backend — covering authentication, Firestore, Cloud Functions, push notifications, and file storage. I take projects from zero to live. That includes UI, backend, payment integration, and full store submission on both App Store and Google Play. I also handle store rejections and post-launch support.

FAQ
Do you build actual blockchain or smart contract functionality?
I specialize in the app layer — wallet UI, live price data, and payment/subscription logic. For custom blockchain or smart contracts, let's discuss scope first.
Can you integrate real-time crypto prices
Yes, using public APIs like CoinGecko or Binance
Do you handle in-app purchases and subscriptions?
Yes — I've shipped this in production, including free trial logic and Google Play Billing.
Will the app store or handle real cryptocurrency?
That depends on scope. Apps handling real funds/custody need extra security work, scoped separately.
Do I own the source code?
Yes, full source code is included in every package.
What do you need from me to start?
Your app idea, any design references, and your preferred crypto data source (or no preference is fine).
