At Upwork (HWS), I train and evaluate Uma, Upwork’s proprietary AI model, for candidate retrieval and query filtering. I benchmark matching across job requirements, freelancer profiles, and filtering parameters to help improve search precision.

At Hugo Technologies, I review multimodal AI responses to STEM prompts and flag incorrect or hallucinated outputs. I’ve annotated over 50,000 text and image data points with 95% accuracy using the Single Review Tool.

As a Technical Support Engineer at Hugo Technologies, I mapped website data for the XAI Extension, testing HTML identifiers with JavaScript and documenting changes. I also work on freelance web projects using HTML5, CSS3, JavaScript, React.js, Systeme.io, and Squarespace.
