What I'm looking for

I'm looking for on-site, rotating-shift work labeling data against client guidelines with high accuracy.

At Invisible Technologies, I lead quality strategy and execution across global AI and data-focused projects. I coordinate workflows across contributors, QA teams, and operations, and use audits and performance trends to recommend corrective actions.

At Samasource (Sama), I designed and delivered training for AI data projects, trained contributors in image and video annotation, and coached Quality Analysts. I also built quality rubrics that improved task accuracy by up to 20% and presented project performance reports to clients.
