About

I'm a San Diego-based staff software engineer specializing in high-scale abuse prevention and ML-powered risk systems. I believe in respecting what came before, researching the legacy I'm building on, and iterating from stable foundations.

When I'm not coding, you can find me reading Hacker News, collecting LEGO Star Wars sets, playing board games, or gaming.
