Hi — I'm Madan (@winklemad).

I find and fix subtle correctness, security, and API-contract bugs by reading the code, then ship the fix with a red→green regression test. No typo fixes. So far that's 30+ merged pull requests into projects owned by OpenAI, Meta, Microsoft, Google, Google DeepMind, Apple, Keras, Unsloth, Mistral, Redis, Qdrant, Vue, Prefect and pydantic — with 60+ more in review across nearly 50 organizations, in Python, TypeScript, Java, Rust, Go and C.

Sponsorship buys one thing: focused hours to read more source and ship more fixes into the tools you already depend on. If a project you rely on has been made a little more correct by one of these, that was the work.
