About

I’ve spent ~7 years building large-scale machine learning systems across cybersecurity threat detection, payments infrastructure, and quantitative finance. I’ve seen startups from the inside at very different outcomes: Level and Caffeine were both ambitious, well-backed companies that ultimately failed, while Doppel became a breakout success. That contrast shaped how I think about markets, execution, and the narrow path from promising company to enduring one. Before that, I did quantitative research. It was intellectually challenging, but not the work I wanted to be remembered for. I studied computer engineering at Waterloo, though I mostly lived for the co-ops. They gave me just enough exposure to the working world to know I eventually wanted to build something of my own. Now I’m building Asymptote with my best friend and long-time co-worker. We’re building a generational cybersecurity company. This is my life’s work. I write at:
