Thirdshelf Loyalty for Retail
An online loyalty platform capable of ingesting millions of transactions from various points of sale (such as LightSpeed, Vend, Shopify, and so on)—analyzing customer behavior, and automating marketing campaigns to drive customer retention and increasing basket size.

As CTO of the company, I built the entire core platform, brought it to market, hired a team of world-class developers, and deployed it to tens of thousands of merchants across North America.

Mozilla Firefox
I was part of the early Firefox team, working on the rendering engine of Firefox, and implementing an industry-first vectorial graphics engine that offered much higher quality and performance than other competing browser engines. I subsequently contributed to Firefox for mobile, developing a performance-optimized multi-threaded architecture.
