Jake has been at Stripe for the last 7 years, 6 of which he's spent working on Sorbet, a type checker for Ruby. His focus is on using types to make Ruby developers more productive: improving the type system, building type-driven tooling, and making sure that type checking is fast.

Jake first became interested in types while attending CMU, meaning he's still a recovering Standard ML enthusiast. Outside of work, he loves anything that takes him outdoors.
