About Me

Full Stack DevelopmentReal-time ApplicationsAI IntegrationCloud Architecture

Hi, I'm a 22-year-old Full Stack Developer who builds complete products from the ground up. I work across the stack: responsive UIs with React, Next.js, Tailwind CSS, and React Native; backend APIs with Node.js and Express; and databases like MongoDB, PostgreSQL, and MySQL.

I like building things that feel smooth and just work. Real-time features with WebSocket and Socket.io, AI models woven into real products, or scaling with Prisma and cloud tools. Frontend or backend, doesn't matter. I go where the problem is.

When I'm not coding, I'm watching movies. Good stories, good details — same reason I like good code.
