Hi, I am Iv, a freelance specialist focused on executing entry-level to intermediate AI training tasks and data annotation. I help developers clean and optimize their models through accurate text labeling, data entry, and intermediate prompt evaluation. While I have a strong foundation in the natural sciences (physics, chemistry, biology) and quantum/mathematical concepts, my services are designed for efficient, everyday data tasks—ranging from simple image tagging to mid-level factual checks of AI responses. I follow project guidelines meticulously and deliver high-quality, manual results.
