What I'm looking for

I'm looking to apply my rubric-based evaluation, Greek-language writing, and data-quality review skills to AI output assessment and content-quality work.

I'm currently working with Mercor as an independent Generalist Expert, applying rubric-based judgment to review and grade AI-generated content.

At Mellon Group of Companies on the National Bank of Greece project, I verified high volumes of structured data, identified inconsistencies and edge cases, and documented resolution quality through CRM systems.

I bring native Greek writing, grammar, and editorial judgment alongside C2 English proficiency, supporting clear evaluation and review of Greek-language AI training content.

My Electrical and Computer Engineering studies at the University of Patras have strengthened my foundation in programming, automation, data analysis, and systems analysis, including simulation work in ATP-EMTP.
