I like typesafety. I built and currently maintain Zod — a TypeScript schema validation library with advanced type inference. I also designed the first proof of concept of tRPC.

I got into open-source while trying to build a medical record software. The startup failed but the technical challenges I encountered have kept me busy for years :) Managing the complexity of an app with over 200 highly-connected tables made the limitations of current validation, API design, and state management tools exceedingly clear.

My open-source projects are tools I built to manage this complexity. I hope they're useful to anyone who wants to build apps in a type-safe, reliable way.

This is roughly enough to keep me alive based on sponsorship income alone. A man can dream.
