`> whoami`

I'm an AI Engineer who enjoys understanding how systems behave beneath the abstraction layer.

My interests sit around LLM systems, Python, backend engineering, and production AI. I like reading unfamiliar codebases, reproducing real bugs, tracing them to their root cause, and turning that understanding into small, focused, well-tested fixes.

Right now, I'm intentionally spending more time contributing to the open-source Python ecosystem.

Open Source Mode

Note

I'm currently focusing on real issues in established Python projects: bug fixes, regressions, edge cases, tests, and framework internals.

`debug`

Reproducing tricky bugs
Root-cause analysis
Edge cases and regressions
Understanding framework internals

`fix`

Small, maintainable changes
Regression coverage
Preserving existing behavior
Clear validation before submitting
