What I'm looking for

I'm looking to contribute linguistic precision, data annotation, transcription, and quality assurance skills to emerging-technology projects where organized, accurate work and creative problem-solving are valued.

I support AI projects at Sigma AI and RWS through data annotation, audio-to-text transcription, content classification, audio segmentation, quality assurance, and metadata tagging.

My 16+ years in business operations include customer support at ModSquad and Foundever, where I resolved technical and account issues through web messaging, calls, and email. I communicate confidently in Polish and English while using international company tools, SAP CRM, TS Matrix, Avaya, Microsoft Office, Teams, and Slack.

Previously, I managed busy security-office operations for MCR Group and BDS Security/G4S Secure Solutions in Dublin. I coordinated teams, handled reports and access systems, monitored site security, and served as a first point of contact for staff, visitors, and management.

I bring linguistic precision, careful organization, creative problem-solving, and reliable support in fast-paced environments.
