01 · About

An engineer in training who ships.

I'm a Computer Science and Engineering undergraduate at Amrita Vishwa Vidyapeetham, Chennai (CGPA 8.08). My foundation is data structures, algorithms and object-oriented design, supported by coursework in databases, operating systems, computer networks and system design fundamentals, and 105+ solved LeetCode problems.

I build and ship full-stack and AI-powered applications: FastAPI backends, React frontends and retrieval-augmented generation (RAG) pipelines. I work mainly in Python, Java and C++, with HTML, CSS and JavaScript on the front end, and I hold HackerRank's SQL (Advanced) certificate.

I currently lead PR at AMCFOSS, Amrita's free and open source software club. I use Linux day to day, practise DSA daily, and I'm looking for a Software Development Engineer internship.
