About me
Tired of slow native development or buggy cross-platform apps?
Need a fast, beautiful React Native Expo iOS and Android mobile app that actually launches on the App Store and Play Store?
I specialize in building high-performance React Native Expo mobile apps using the latest 2026 Expo tools (EAS Build, new architecture, OTA updates), vibe coding with Claude Code, Lovable AI, Firebase, Supabase, and full API integration.
From idea to live app in days, including AI features, trading bots, e-commerce, or custom SaaS mobile apps.
