About me
I build complete products, not just apps — iOS, Android, web, backend and deployment, handled by one developer.
Six years in, 100+ apps delivered: small business tools, hobby projects, and complex platforms like ride-hailing apps with live tracking and multi-vendor marketplaces.
Native Android and iOS, Flutter and React Native for cross-platform, React on the web, Node.js and Firebase on the backend. Clean architecture, documented code, and full source handed over every time.
Every project starts with a written scope and a fixed price. I reply within 2 hours.
