What I'm looking for

I’m looking for remote, hybrid, or onsite work where I can deliver high-quality AI data annotation and LLM evaluations, meet target-driven SLAs, and continuously improve QA accuracy with a collaborative team.

I’m a results-driven Data Annotation and LLM evaluation professional focused on maintaining 95%+ annotation accuracy while processing high-volume datasets. In my current role, I annotate and label AI training datasets, validate 1,000+ data entries weekly, and reduce annotation errors by 20% through detailed quality checks and review procedures.

I also bring strong business operations experience, including improving operational efficiency by 35%, increasing business revenue by 40%, and reducing stock loss by 20%. I’ve supported sales growth (30%+), managed 50+ client deliveries monthly, and led teams of 5–10—so I can work confidently in remote, fast-paced, target-driven environments.
