What I'm looking for

I'm seeking remote roles where I can apply AI training, data annotation, and prompt testing to improve model quality, collaborate cross-functionally, and contribute to impact-driven AI products with opportunities for skill growth.

I am an AI and data trainer with hands-on experience training large language models and evaluating AI-generated video and text.

At Invisible Technologies, I assess realism, motion, tone and visual accuracy in AI-generated video, flagging inconsistencies and conducting prompt-based testing. As a freelance data trainer I reviewed and corrected model outputs and helped build accurate, diverse datasets.

I work effectively in remote settings, use no-code tools like Notion and Slack, and hold a BA in Communication plus Google AI Essentials and TESOL certifications; I seek roles where I can improve model quality and workflows to deliver measurable impact.
