What I'm looking for

I seek roles where I can ensure high-quality annotated data for AI, mentor annotators, improve QA processes, and work with ethical NLP practices.

I am a detail-driven data annotation and quality assurance specialist with hands-on experience labeling text, audio, and image data to train AI models. I consistently follow project-specific guidelines, use tools like Labelbox and CVAT, and maintain high accuracy standards.

As a Quality Analyst, I developed QA checklists, implemented feedback loops, and raised annotation quality to a 95%+ threshold while mentoring new annotators to reduce onboarding time. I collaborate with annotators and project managers to resolve ambiguous cases and improve workflow clarity.

I hold a Second Class Lower degree in Sociology and combine strong research, communication, and teaching skills with knowledge of NLP, bias mitigation, and model evaluation to deliver reliable, ethically minded datasets for machine learning projects.
