Building mobile apps that are smarter, faster, and ready for the AI era.
For me, development isn't just about writing code it's about creating apps that solve real problems and deliver real results. In 2026, that means combining solid React Native expertise with AI-powered tools to ship production-ready apps faster than ever.
I'm a React Native developer specializing in health & wellness apps and startup MVPs. I use AI-enhanced workflows (Cursor, Claude, GitHub Copilot) to deliver clean, scalable code at speeds that traditional development can't match.

════════════════════════════════
→ Health & Wellness Expert: Built apps for ADHD management, fitness tracking, and mental health—I understand the unique challenges of health data and user engagement.
→ AI-Accelerated Development: I leverage AI coding tools to deliver 2-3x faster without sacrificing quality. You get production-ready code in weeks, not months.
→ Startup-Friendly: I've helped founders go from idea to App Store. I understand MVPs need speed AND scalability.
