Marco Rocha

AI engineering that ships, with receipts

I build LLM workflows that survive real traffic — and prove it with traces, before/after metrics, and public repos.

§ 01 — ABOUT

I'm Marco — AI engineer building production workflows for teams that need automation they can trust at 03:00. The brief varies: document pipelines, agent orchestration, internal copilots, back-office automation. The shape is always the same — too much manual work, not enough headcount, zero tolerance for hallucinated answers.

Stack on the right. Every system ships with traces (Langfuse), typed guardrails (Pydantic), and a CI/CD path that doesn't depend on my laptop. If it can't be re-run against last week's input and produce the same answer, it's not production.

Currently shipping one project per month through 2027 — public repos, real users, measured before/after. Open to advisory engagements and scoped builds across LLM ops, agent systems, and back-office automation.
