Featured build — end-to-end: LLM orchestration, validated SQL, eval harness, and the UI.

Olist Dashboard AgentAsk a question in plain English, get a live dashboard. The LLM writes a JSON + SQL spec; Zod validates it, DuckDB runs it, a retry loop self-corrects, and an LLM-as-judge eval harness keeps it honest.

The AI wrote the SQL. I made sure it couldn't lie.

Olist Dashboard Agent — LLM-generated analytics dashboard with validated SQL

ABOUT ME

I talk to LLMs more than humans now. They listen better, never schedule meetings, and if they hallucinate at least they are creative about it.
What I DO
01

AI Engineering

I make the model show its work. Trust issues, professionally applied.

02

Frontend for AI

Designing loading states for a thing that thinks for 20 seconds. A real job, I promise.

03

Backend & Data

Where the SQL the model wrote gets supervised. Someone has to.

EXPERIENCE

6 years of shipping code
and sitting through
demos where the AI ‘almost works.’ Mine ships.
