I build systems that meet cameras, electrodes, users, and imperfect inputs as they actually are — AI engineering undergrad @ Amrita Vishwa Vidyapeetham.
gh pr list --author @me --state=all
I contribute upstream where a small, precise change removes a real developer paper-cut — then add the regression test or documentation that keeps it fixed.
381 pull requests merged to date — 85 upstream across eleven labs (tabled below), 5 in peer repos, 22 shipping a production e-commerce build through PRs (Sree Vartali Sarees — CMS, store, cart, orders, WhatsApp), and 269 on my own projects via PR-driven workflows (projX, CallPilot, mano-os, pokermind).

Build it from scratch at least once — the magic disappears, the understanding stays.
If you can't reproduce it, you don't understand it yet.
Real data over clean examples — messy input teaches what tutorials hide.
Know what's underneath your abstractions. They all leak eventually.
