About

Joseph Mizrahi

I'm Joseph Mizrahi, a Lead Software Engineer on Disney's Transactional & Payments team, building the commerce experience behind Disney+, Hulu, and ESPN, and helping Disney's client-side commerce teams use AI in day-to-day engineering.

I started in 2015 at MLB Advanced Media, building sites like MLB.com, then moved with the BAMTech spin-out, which became Disney Streaming and is now part of The Walt Disney Company. Along the way I worked on NHL.com, helped launch Disney+ and take it to new markets around the world, and grew into commerce for Hulu and ESPN. More than a decade and thousands of pull requests later, I'm still building how fans subscribe, now including MLB.TV on ESPN.
