🎓 About Me

I'm a final-year B.E. Computer Science student at St. Joseph's Institute of Technology, Anna University, Chennai (graduating 2027, CGPA: 8.08). I'm passionate about building AI-powered applications, RAG systems, and full-stack solutions that solve real-world problems.

Currently preparing for campus placements, contributing to open-source projects (GSSoC 2026), and maintaining an active AI and RAG portfolio.
