What I'm looking for

I seek a role leveraging my annotation and QA expertise where I can improve data quality, collaborate with engineering teams, and contribute to model performance and analytics in a deadline-driven, data-focused environment.

I am an experienced Data Annotation QA professional with a strong track record in classification, segmentation, bounding-box annotation, and quality assessment for large-scale data projects. I have worked on annotation and linguistic QA for major tech companies, leveraging tools like Radar, JIRA, and SQL to improve data accuracy, reduce processing time, and ensure culturally appropriate outputs.

I collaborate closely with engineering teams, external partners, and project managers to evaluate outsourced work, track and resolve defects, and extend datasets for model improvement. I bring meticulous attention to detail, proven delivery under deadlines, and a commitment to driving data-driven insights as a Data Analyst.
