About Jeffery
I help teams improve AI quality and technical projects by delivering precise multimodal data annotation, rigorous scientific analysis, and clear technical reports. With hands‑on experience as an AI data evaluator, battery researcher, and STEM educator, I combine lab‑grade accuracy (XRD, SEM, EIS) with strong communication and native‑level English. Typical deliverables: content ratings & annotations, data analysis & visualizations, research summaries, and stakeholder‑ready presentations. Available for short‑term gigs and ongoing projects.
