About Me

I am a Full Stack Developer & AI Engineer currently pursuing myB.Tech in Electronics and Communication Engineering. I bridge the gap between hardware logic and software scalability.

My core expertise lies in architecting web and mobile ecosystems using Next.js, TypeScript, and React Native. On the backend, I build robust data pipelines with Node.js, Python, and PostgreSQL/MongoDB.

I love competing in Hackathons to build innovative solutions under pressure.
