I’m a freelance research professional with 12+ years of experience in advanced web research and recent hands-on work in AI data quality. I combine deep investigative skill with clear, structured analysis—whether I’m locating hard-to-find information or evaluating complex AI outputs with precision. My AI work includes evaluating large-scale AI-generated image datasets, such as a 1-million-image face-swap project (assessing accuracy, identity preservation, and expression alignment) and a 2-million-plus-image subject-addition project (identifying artifacts, nonsensical content, and prompt inaccuracies). I delivered structured pass/fail evaluations with detailed issue categorization to support model training and data quality improvement. I’ve also performed millisecond-level audio annotation using Labelbox, marking speech segments, pauses, interruptions, and acknowledgements in user–AI conversations to build reliable training data. In research projects, I work with open-source materials, multilingual searches, and alternative engines to uncover and verify information with precision. I organize complex findings into clear, structured outputs clients can rely on. Available for ongoing or project-based work (30+ hrs/week). Most contracts currently shown as “in progress” are paused and not active.
