What I'm looking for

I’m looking to support AI training teams with rigorous, guideline-based data quality review. I want a role where my linguistic validation, edge-case detection, and clear reproducible feedback directly improve dataset reliability and contributor performance.

I’m an AI data quality specialist focused on annotation, content evaluation, and guideline-based quality review. With 3+ years of experience, I validate Ukrainian language data by checking grammar, spelling, and sentence structure for accuracy, consistency, and compliance with project standards.

I strengthen AI training outcomes by identifying systematic mistakes, guideline misinterpretations, and edge-case failure points, then documenting reproducible error traces. I provide clear, metacognitive feedback that helps contributors align expectations with final approved outputs—while maintaining quality under time constraints.
