About

I didn't take the conventional path into software engineering. At age 18, I built an EdTech startup called "iTopper" that reached 4,000 installs. It failed, but I learned more from that than most people learn in four years of college. And I kept building. Most recently I served as Technical Lead at Paywaz, a US fintech startup, where I architected their entire blockchain-powered payment infrastructure from scratch.
