What I'm looking for

I'm looking for operations, project coordination, or AI data quality work where I can manage documentation, improve processes, validate data, coordinate stakeholders, and support cross-functional teams.

I've validated AI-generated vehicle license plate recognition results at XELENTEPIXEL LDA., correcting annotation errors and improving OCR data accuracy.

At Partícula Extravagante, I coordinate administrative and operational activities across AI data annotation projects, managing contracts, invoices, funding documentation, records, and deadlines while liaising with public institutions, suppliers, and multidisciplinary teams.

My experience also includes event production at Cartola de Artistas, audiovisual data logging at Endemol Portugal, and journalism and production at Rádio Observador. I bring structured data review, documentation management, stakeholder communication, and quality-focused execution to fast-paced teams.
