Hi, I'm Jeongho Nam (Samchon).

I build the TypeScript compiler plugin ecosystem — and the libraries that prove what it makes possible.

At the foundation is ttsc, my TypeScript compiler adapter and plugin host. On top of it, I build libraries like typia that turn type information into runtime capabilities conventional TypeScript can't deliver:

  • ttsc — TypeScript compiler adapter and plugin host that powers the entire ecosystem
  • typia — Ultra-fast runtime validators, serializers, and LLM function calling schemas generated directly from TypeScript types
  • nestia — Type-safe NestJS toolchain with automatic SDK and Swagger generation
  • autobe — AI agent that generates production-ready backend applications with 100% compilation success

My signature work is the function calling harness — turning TypeScript types directly into LLM function calling schemas with validation feedback that drives success rates from single digits to 100%. Featured writings:

Your sponsorship keeps this ecosystem maintained and freely available.

@samchon

Hope my projects to be helpful for many developers.
