Thomas Cosnefroy

I’m an Artificial Intelligence Independent Contractor focused on evaluation, writing, and correction of prompts for training confidential pre-release AI models (RLHF). I annotate and qualitatively evaluate hundreds of audio tracks, and I assess model outputs and text responses to help improve AI performance. I take pride in being detail-oriented and consistent across large-scale tasks. My native language is French, and I have a C1 English level as my work environment is mainly english-based.

Before my AI work, I built practical experience through an operations-focused internship and front-desk roles. At Bosch France HQ in the Logistics Department, I supported internal communication updates, assisted with English negotiations for international transport of confidential vehicles, and helped integrate incoming and outgoing shipments into a dedicated software system. In front desk positions, I handled client reception, telephone inquiries, appointment scheduling, and cash register opening/closing in high-volume service settings.

My core strengths sit at the intersection of AI/data quality and careful coordination: annotation/labeling, prompt engineering, rewriting, classification, and model output evaluation—grounded in confidentiality. Alongside my AI/data work, I’m comfortable with office software (Word, PowerPoint, Excel) and I enjoy clear feedback loops that help me improve quickly and deliver reliable results.
