I'm a Full Stack Developer who builds web apps, mobile apps, SaaS platforms and AI systems with React, React Native/ Flutter, Node.js and Python, and adds AI and LLM features where they make the product better. One developer for your frontend, backend, web app, mobile app, and AI layer. Over the last 8+ years, I've helped startups and established companies launch, scale and improve products and systems, combining strong full-stack development with practical AI solutions that solve real business problems.
