Aritra

I'm an Operations Research Scientist at Lyric, where I write code to make supply-chain operations faster and more reliable with linear programming and algorithms. I recently finished my Master's in Computer Science at the Chennai Mathematical Institute, graduating with a Medal of Excellence.

Most of my path has run through open source. I was a Google Summer of Code contributor twice — with Mathesar in '23 and omegaUp in '24 — and have since mentored for it. In '25 I built on Braidpool through Summer of Bitcoin, and spent a summer at the National University of Singapore studying parameterized algorithms and the hardness of the Hamiltonian Path problem. I'm an Expert on Codeforces, and I love algorithms, mathematics and heuristics.
I play football, badminton and practice calisthenics, and love watching Real Madrid matches.
