What I'm looking for

I’m looking for remote, guideline-driven AI data work—multimodal annotation, search evaluation, and fact-checking—where accuracy, confidentiality, and clear documentation matter. I’m at my best owning workflows independently and adapting quickly to updated rubrics.

I’m a reliable independent contractor with over 10 years of experience in retail operations and management, and I’m currently specializing in AI Data Evaluation and Multimodal Analysis. I leverage my university background in Media and Psychology to provide nuanced data annotation with strong accuracy and consistency.

In my AI work, I evaluate and annotate image and video for object identification, counting, and spatial layout descriptions to support Computer Vision model training. I also review AI outputs to choose superior responses based on prompt alignment and visual fidelity, while performing fact-checking against reliable online sources to reduce errors and hallucinations.

I thrive in remote, guideline-driven environments where confidentiality matters. I’m comfortable navigating complex and frequently updating instructions, documenting findings clearly, and maintaining strict adherence to project requirements, NDAs, and intellectual property protocols.
