- Personally built and shipped a complete AI agent system used by real customers.
- Deep experience with LLM orchestration, RAG, structured outputs, function calling, and evaluation frameworks.
- Strong TypeScript skills.

- Strong systems design and architectural judgment.
Strong Plus Factors:
- Former founder or founding engineer.
- Experience building accuracy-critical AI applications.
