What I'm looking for

I’m looking for remote or flexible work where I can label and validate high-quality ML datasets for NLP and computer vision, uphold strict client requirements, and keep improving accuracy and efficiency through clear guidelines and QA collaboration.

I’m a detail-oriented Data Annotation Specialist with over 3 years of experience labeling, validating, and optimizing datasets for machine learning and AI models. I’ve worked across NLP and computer vision tasks, applying detailed project guidelines to keep labeling accurate and consistent.

In my roles (freelance remote and client-based), I’ve maintained quality benchmarks, completed quality checks, and collaborated with QA teams to ensure dataset reliability. I also focus on efficiency—improving workflows through task prioritization and supporting teams by assisting in training new annotators and improving overall performance.
