i build things because i'm curious and think why not.

right now that's ml systems in healthcare—messy clinical data, tight timelines, real consequences if things break.

research software engineer at sunnybrook in toronto. the nlp person. if it involves clinical text, it ends up on my desk.

i learn by building. i see a paper, i implement it. if it breaks, i figure out why. i reverse-engineer undocumented systems because that's usually where the real problems are.
