Builder. Tinkerer.
Problem solver.

I'm a 3rd-year B.Tech Computer Science student at SRM Institute of Science and Technology, Chennai, passionate about building systems that make a real difference.

My work spans full-stack web development, AI/ML engineering, and IoT — I've shipped everything from production CRM platforms and real-time dashboards to a drone that detects landmines with 92% accuracy.

I'm also the founder of ComputerBaazi, a platform making affordable electronics accessible, and I've led community STEM outreach programs recognized by law enforcement.
