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 — from building responsive UIs with React, Next.js, Tailwind CSS, and React Native, to writing backend APIs with Node.js and Express, to managing databases like MongoDB, PostgreSQL, and MySQL.

I enjoy creating end-to-end solutions that feel smooth and practical. Whether it's adding real-time features with WebSocket and Socket.io, integrating AI with OpenAI and Gemini, or scaling apps with Prisma and cloud tools, I like working across both frontend and backend to make things work well.

When I'm not coding, I'm usually watching movies — I just enjoy a good story and the little details that make it fun to watch.
