About Me

I am a Full Stack MERN Developer with 4+ years of total web development experience, including 2+ years specializing in React.js, Node.js, Express.js, and MongoDB. My journey involves transforming complex problems into elegant, maintainable solutions, from database architecture to intuitive user interfaces.

Currently, I specialize in building real-time applications and robust Web3 platforms. I have a proven ability to own features end-to-end — from database design and secure API development to responsive UI and production deployment. I am also experienced in working with AI-assisted tools to ship clean, maintainable code faster.
