Frontier and vertical models have moved past what generalist annotators can produce. Clinical reasoning, tax treatment, contract review and structural engineering all require credentialed professionals writing and adjudicating the data.
Latin America has large licensed professional populations — physicians, attorneys, CPAs, engineers — with strong English and rates that make expert-written data economically viable at volume rather than in token quantities.
We verify credentials before anyone touches a task, and we pair experts with annotation leads who translate their judgement into rubrics the wider pod can apply. That keeps expert hours focused on the work only they can do.

The Challenge
Generalist annotators produced plausible but legally wrong reasoning, and the team had no scalable way to route contested labels to a qualified reviewer.
The Solution
A network of licensed attorneys wrote reference reasoning traces, designed the scoring rubric, and served as adjudicators for contested labels produced by the wider annotation pod.
The Results
- Expert-written reasoning traces for every task category
- Rubric handed off so generalists could handle 70% of volume
- Contested labels routed to an attorney within one business day
- Credential verification completed for 100% of expert contributors
- Expert hours concentrated on adjudication rather than bulk labeling

Use these questions to evaluate candidates during your interviews.
Technical Questions

- • How do you document the reasoning behind a label so a model can learn from it?
- • What are the failure modes of a model in your domain that a layperson would miss?
- • How do you handle a case where the professionally correct answer is genuinely contested?
Cultural Fit Questions
- • How do you explain a domain decision to an ML engineer with no background in your field?
- • Describe a time you had to overrule a confident but incorrect answer.
- • How do you keep consistency across a panel of experts who disagree?
