OneformaImageEvaluation Rating

I performed search-relevance evaluation at OneForma, rating search result intent and quality using multi-dimensional rubrics. I annotated both text and images for classification, span tagging, and comparison in support of ML training. My work emphasized accurate data extraction and rubric adherence across diverse data sources. • Rated search result relevance, freshness, and authority for locale-specific queries. • Annotated text and images for classification and tagging tasks. • Captured and validated structured data from web pages and screenshots. • Supported active machine learning projects with accurate data labeling.

OtherTextRLHF

As an AI Data Specialist (Freelance) at Outlier, I annotated and ranked large language model responses to support reinforcement learning from human feedback (RLHF). I evaluated outputs for factual accuracy, coherence, and adherence to rubrics while providing structured rationales for each judgment. I contributed to alignment and quality by identifying and flagging hallucinations, bias, and safety issues. • Annotated and ranked responses in reasoning, mathematics, and coding tasks. • Conducted independent web research to verify accuracy and authority. • Maintained calibration and inter-rater agreement using strict guidelines. • Evaluated finance-domain prompts utilizing FinTech quantitative skills.
