What I'm looking for

I seek remote roles contributing to high-quality ML datasets where I can apply linguistic expertise, annotation, QA, and guideline development within collaborative teams.

I am a linguist and data annotation specialist with 4+ years of experience transcribing, MTPE/post-editing, and collecting focused datasets to support NLP, ASR, and computer vision projects. I work reliably under detailed guidelines to produce consistent, high-quality labeled text, audio, and image data, and I contribute to QA cycles and guideline improvements to reduce inter-annotator disagreement.

I hold a BA in Linguistics and have self-studied core ML concepts and annotation best practices, with hands-on experience using Labelbox, CVAT, and Prodigy plus CSV/JSON and spreadsheet workflows. I am adaptable to remote, distributed teams, available for flexible schedules, and committed to secure dataset handling, metadata management, and reproducible dataset versioning.
