On top of it, I build libraries like typia that turn type information into runtime capabilities conventional TypeScript can't deliver:\n\nttsc — TypeScript compiler adapter and plugin host that powers the entire ecosystem\ntypia — Ultra-fast runtime validators, serializers, and LLM function calling schemas generated directly from TypeScript types\nnestia — Type-safe NestJS toolchain with automatic SDK and Swagger generation\nautobe — AI agent that generates production-ready backend applications with 100% compilation success\n\nMy 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%.
