About

I solve hard technology problems that make people's lives better.

It started as a love for computers — writing code as a kid trying to make video games, until the Canadian Computing Competition pulled me into programming contests. It was never enough to just solve a problem; I cared about building the skills to reconstruct solutions from scratch — the theory of problem-solving itself. At Waterloo I became a 2× ICPC World Finalist (St. Petersburg 2013; Morocco 2015, where we finished 13th in the world, 3rd in North America, and 1st in Canada), and later a 2× World Finals Judge. That discipline became the Theory of Problem Solving, and it still shapes everything I do.

The same curiosity put me early on the AI wave. I studied AI and Mathematics at amii and Waterloo, built data products at Meta, Palantir, Dropbox, and Pure Storage, then founded Forethought, the most advanced Agentic AI for Customer Experience: $115M+ raised, TechCrunch Disrupt champions, over a billion customer interactions a month, and acquired by Zendesk in 2026 — reportedly their largest acquisition ever. I remain Forethought's Chairman.

My full-time focus now is Espa Labs, where I'm founder & CEO. Espa is the AI-native executive assistant: it plugs into your email, calendar, and tasks, and doesn't just suggest — it sends the email, books the meeting, tracks the follow-up. The mission is executive-level support for everyone, not just those who can afford a full-time EA. Espa has been featured in Fast Company and on CNBC. And we're hiring — if you want to build the assistant everyone deserves, come find us.

Quantum computing will be the next technological wave, and I'm approaching it the way I approach AI and algorithms: understand deeply, from first principles, before building. I publish research in mathematical physics and machine learning, dissect quantum algorithms like contest problems, and write Understanding the Universe — physics rebuilt from intuition. Give it a decade.

I grew up in inner-city Toronto, the child of St. Lucian immigrants who went to Canada in search of a better life for their kids. Getting from there to here took all of it — the luck of finding computers early, years of hard work, an education, and at every step someone who opened a door: a teacher, a mentor, a chance. That gratitude shapes how I spend my time and capital: investing in and mentoring the next generation, and spreading access to technology, entrepreneurship, and education. It's part of why I'm building Espa — and why I write honestly about the founder journey, expensive lessons included, in Sum of My Mistakes.
