I'm Saivedant Hava, an AI/ML engineer. I work on the open-source tools the industry quietly depends on, hyperparameter optimization, LLM infrastructure, and model serving, usually by finding the bug everyone assumed someone else already caught. I read the code people trust, find what it swore wasn't there, and open a PR with a test that proves it. Turns out "used by thousands of developers" and "actually tested" are not the same thing.
Active contributor across top-tier AI/ML repositories with merged PRs in production.
