I'm a senior mobile developer with 7 years of experience building React Native apps for iOS and Android. I work on apps that run in production and handle real users. 📱 WHAT I BUILD ✅ React Native and Expo apps from first screen to App Store ✅ AI features inside mobile apps using OpenAI and LLM APIs ✅ Apple Watch and wearable integrations ✅ Real-time features and push notification systems ✅ Node.js and Firebase backends powering your mobile product ✅ App Store and Google Play publishing via EAS Build and Fastlane ✅ Bug fixes and performance work on live production apps 🏆 WHAT I'VE ACTUALLY BUILT Healthcare app — built and maintained a mobile app used by real patients over a multi-month engagement. Clean UX, stable performance and consistent 5-star delivery throughout. Fitness iOS app with AI — integrated LLM API features into a React Native app running on device in production. Full chain from API integration through to structured output on screen. Apple Watch companion — built a health and performance app for wearable that connects watch data to the main iOS app. Most React Native developers can't touch this level of native integration. Live production crash fix — a client's Expo app was crashing in production. Fixed it before they noticed. Their words: "fixed the bug before I even noticed it. Quality and delivery time were beyond my expectations." Long-term React Native project — maintaining and shipping new features for over a year with consistent 5-star delivery across every milestone. ⚙️ HOW I WORK I communicate early when something is off and flag problems before they become crashes. Clients describe me as reliable, committed to quality and detail-oriented across every engagement. 💻 TECH STACK React Native · Expo · TypeScript · iOS · Android · Ionic · Capacitor.js · Firebase · Supabase · Node.js · OpenAI API · EAS Build · Fastlane · Push Notifications · App Store · Google Play · React · Next.js · CI/CD · GitHub Actions 🎯 WHO I WORK WITH Startup founders and product teams building real mobile products.
