I build in React, Next.js, and TypeScript to ship fast, maintainable web apps, then use Node.js, PostgreSQL, and AWS to keep the backend reliable and scalable. For AI features, I integrate OpenAI APIs and Cursor into workflows that automate tasks and add real product value. I also use Flutter when a project needs a polished cross-platform mobile app.

I build full-stack web applications with React and Next.js, integrate Node.js APIs, and deliver mobile app development with Flutter and AI development that scales.
