What I'm looking for

I seek remote roles in AI data annotation or digital operations where I can apply precise dataset preparation, QA, and productivity tools to improve model performance and operational efficiency.

I am a detail-oriented AI training and digital support specialist with two years' experience in data labeling, dataset preparation, and quality assurance for machine learning projects. I consistently deliver high-quality datasets—annotating over 10,000 images with up to 98–99% accuracy—and streamline operations using AI platforms and productivity tools.

I work effectively in remote, global teams and communicate at C2-level English, supporting research, documentation, and executive operations while applying tools like ChatGPT, Notion, Google Suite, and Adobe Creative Cloud to improve workflows and project outcomes.
