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.

🚨 IMPORTANT — Do not sponsors at this level unless you represent a corporation that a) has a valuation above >$10 billion and b) depends on Zod as part of a developer-facing API. This is very important and serious. 🚨

To my delight, a number of AI and API tools rely on Zod as a canonical representation of user-defined types for structured outputs, tool inputs, etc. Some of these tools are built and maintained by companies with valuations over $10B. This is a special sponsorship tier intended exclusively for these companies. All Diamond tier perks apply.
