⭐ Senior AI React Native Mobile App Developer
✅ $10k+ Earned on Upwork with successful client projects
✅ 50+ projects completed

If you're building a mobile app and need someone who can handle the full picture, frontend, backend, and AI integrations, you're in the right place.

I've spent 6+ years building production-grade mobile apps with React Native and iOS (Swift/SwiftUI), and I pair that with solid backend experience, so you're not stitching together two freelancers for one project. Whether it's a clean consumer app or a complex SaaS product, I build things that actually ship.

Lately, a big chunk of my work has been adding AI to mobile — think LLM-powered features, smart assistants, on-device ML, OpenAI/Claude API integrations. If you want your app to feel intelligent, I've done that work.

What I typically build:

✅ React Native apps (iOS + Android) from scratch or existing codebases
✅ Native iOS apps with Swift/SwiftUI
✅ AI-powered features — chatbots, recommendations, voice, vision
✅ Backend APIs (Node.js, REST/GraphQL) that connect it all
✅ MVPs for startups that need to move fast without cutting corner

🙌 If it's a yes, it will be a long-term and profitable partnership for both of us. Let’s chat.
