Engineering leader with a builder's mindset

Driven software developer from California with a passion for programming since age 12. I lead teams that ship production systems at extreme scale — processing petabytes of security telemetry, half a million ad-tech bids per second, and tens of thousands of financial transactions in real time.

Currently Tech Lead for Cyber Security at nPro, I balance 80% hands-on engineering with 20% leadership — mentoring developers, driving hiring, and architecting ML/LLM-powered threat detection across heterogeneous infrastructure.
