What I'm looking for

I’m looking for remote work where my evidence-grounded annotation and UI/workflow interpretation skills improve training datasets and evaluations. I want clear guidelines, strict quality standards, and collaboration with distributed teams on next-gen AI agents.

I’m a highly analytical, detail-oriented AI Data Professional with a proven track record delivering high-fidelity training datasets and evaluations for frontier machine learning models. I distinguish evidence from assumptions, so my written rationales stay rigorous, well-reasoned, and strictly grounded in what’s observable.

I specialize in screenshot analysis, UI interpretation, and structured complex annotation across diverse software environments—supporting multi-modal interface evaluation, text classification, and semantic alignment. In remote production queues, I provide critical feedback loops, aiming for 99%+ compliance with strict orthographic and formatting guidelines while collaborating effectively with distributed global teams to optimize next-generation AI agents.
