01 · About Me

Passionate about
building things
that matter

I'm a Full Stack Developer pursuing B.Tech in Computer Science at Noida International University (CGPA 8.5/10), deeply focused on crafting production-ready applications that are both performant and elegant.

From responsive React interfaces to resilient Node.js APIs and multi-chain Web3 integrations — I love turning complex requirements into clean, scalable engineering solutions.

Beyond the keyboard, I lead NIU's Technical Club, write technical content on Web Development and Blockchain, and actively mentor the student developer community.
