What I'm looking for

I seek a role where I can apply precise annotation and analysis skills to improve AI models, collaborate cross-functionally, and leverage data-driven decision-making in a growth-oriented, impact-focused team.

I am an AI model trainer with hands-on experience evaluating multimodal outputs and delivering high-volume, high-accuracy annotations to support model fine-tuning and RLHF. I partner with cross-functional research teams, apply structured comparative judgment, and use specialized labeling tools to improve generative output quality.

I also bring merchandise direction experience managing purchasing strategy, vendor relationships, inventory optimization, sales analysis, forecasting models, and cross-functional collaboration to drive profitability and operational efficiency.
