Production AI. Distributed systems. Security.
13+ years shipping software. 100K+ users on live AI products. $400M+ in fintech assets protected. 40K+ telematics devices streaming.
Director of Information Security at Lavender. Backend at BlockFi. Elixir at AAMP Global. Co-founded a startup, scaled engineering from 1 to 15.
Bias toward clarity, observability, and predictable failure. The prompts here came from the real problem of teaching 14 other engineers to use AI without making their code worse — which is where the failure-mode framing comes from.
