AI data annotation and QA specialist turning operational data into reliable, error-reduced outcomes.
What I'm looking for
I’m an AI Data & QA Specialist with 10+ years of experience evolving from operations and inventory/logistics management into specialized AI data annotation, data validation, and quality assurance. I combine analytical thinking with hands-on execution to improve data accuracy, reduce errors, and strengthen decision-making with real operational discipline.
I’ve led end-to-end warehouse and supply chain workflows—improving inventory accuracy (~20%), reducing picking/dispatch times (15–25%), and strengthening traceability using Excel-based systems. On remote AI training projects, I manage QA for labeling and validation (including LiDAR/segmentation-style review), coordinate global teams, and support onboarding with tools like Loom—always focused on efficiency, continuous improvement, and consistent quality.
