What I'm looking for

I seek roles focused on high-quality data annotation and QA within collaborative, process-driven teams where I can lead improvements, train annotators, and ensure datasets meet stringent accuracy standards.

I am a detail-oriented data annotator and QA specialist with 5+ years of experience producing and validating high-quality labeled datasets for machine learning and AI systems. I have hands-on experience across image, video, text and LiDAR annotation, maintain accuracy above 95%, and regularly collaborate with engineers and project managers to resolve ambiguities and improve data quality.

I have led annotation tasks, supported onboarding and training, designed peer-review and validation processes that reduced dataset errors, and implemented workflow improvements that increased team efficiency and consistency. I thrive in cross-functional teams, adapt quickly to evolving guidelines, and document processes to promote standardization and reproducible results.
