About

I’m a native English-speaking AI trainer and evaluator with advanced French, focused on helping teams build higher-quality AI for real business and customer-service needs. In my recent work with Snorkel AI and Handshake AI, I contribute to multimodal evaluation and training—covering text, image, and video—through tasks like pairwise preference ranking, rubric and prompt writing, critique and question writing, data labeling, and fact-checking.

Before moving deeper into AI evaluation, I built strong operations and customer-service experience through more than eight years managing daily workflows, handling inquiries and complaints, coordinating logistics and payments, and supervising staff and drivers. I also support language and communication needs through English tutoring and translation-focused documentation work, and I’m especially interested in AI projects related to business operations, customer support, evaluation, and English–French language tasks.
