After graduating from Cornell in 2005 with an undergraduate degree in computer science, Jae worked as a software developer in Silicon Valley, first at Amazon (where he worked on the Alexa digital assistant), then later at Yelp, where he led their mobile app development team. After getting the blockchain bug, Jae created the Tendermint BFT consensus algorithm and the Tendermint Core blockchain engine, with the intent of creating a provably secure proof-of-stake algorithm. In addition to Tendermint, Jae is also the creator of Cosmos.
