services · for teams that shipped an AI feature

I build LLM features and I measure them.

Agents, RAG, NL-to-SQL, with eval harnesses and cost guardrails, so the AI feature you shipped stops surprising you. For seed to Series A teams with no ML hire yet, and for agencies that need white-label LLM capacity.

02 / how it works

  1. step 1

    20-minute call

    You show me the feature. I ask where it fails and what it costs.

  2. step 2

    Written scope in 24 hours

    One page: what I will deliver, when, for how much. You reply yes or no.

  3. step 3

    Work starts within a week

    Daily written updates. You see the golden set before you see a slide.

03 / questions

Which hours do you work?
Roughly 09:00 to 16:00 CET and 09:00 to 13:00 US Eastern are live overlap. Everything else is async with a written update every day.
How do you invoice?
Wise or Payoneer, in USD or EUR, as an individual. PayPal if you insist. Builds are 50% up front, the rest on delivery.
What about the contract and IP?
A one-page agreement: scope, price, payment terms. All IP is assigned to you on payment. No exclusivity either way.
What if the audit finds nothing wrong?
You keep the golden set and the report. That is a measured 'it works', which is worth more than the assumption.
