About Me

I'm a Java Developer and B.E. Computer Science student at SRM TRP Engineering College, Trichy (2027 batch), with a genuine passion for building systems that are not just functional — but well-engineered.

My experience spans the full stack — from Spring Boot microservices and REST API development to React frontends and MongoDB/PostgreSQL databases. I interned at VDart Inc. where I built a production Course Learning Platform serving 50+ users.

Beyond code, I've led national-level technical events as Vice President of Code Crafters Club and serve as Webmaster of the IEEE Student Branch. My IEEE EPICS project was selected and funded by IEEE globally.

My final year project explores cryptographic authentication — combining Device-Bound Authentication with Zero-Knowledge Proof protocols for enterprise & IoT security.
