Leading Enterprise Applications at Roblox

Hi, I'm John. I make IT feel easy for the people who rely on it.

For 15 years I've worked across IT management, systems and software engineering. I built IT from scratch at Verkada, and today I look after identity, SaaS, AV and AI governance for about 3,000 people at Roblox — while staying hands-on.
