I push tools past what they were built for.
That's where the real limits are. Usually the simplest thing still standing is the answer.
Lately that's detections in security: detecting phishing emails at Cisco, detecting Kremlin talking points in Czech comments online. Before that, a browser CLI for AI agents, and whatever's on the soldering bench.

Cisco
Senior ML engineer on anti-phishing - the engine deciding if an email is trying to hurt you, at enterprise scale.
about
Theoretical biophysics by training. Open quantum systems, Redfield equations. The math still holds, the abstraction is what comes in handy.
From there: data scientist, then ML engineering. Now focusing on detections.
Off-keyboard I'm on rock: bouldering, sport routes, the odd alpine multipitch.
