I am an AI Data Specialist and Prompt Engineer with hands-on experience in LLM data annotation, evaluation, and prompt optimization. I work on improving generative model performance and reducing factual errors, with multilingual annotation capabilities (PT/EN/ES). I am currently pursuing a Technologist degree in Artificial Intelligence at Universidade Cruzeiro do Sul (expected 2027), with a focus on Big Data, Python, Data Analysis, Machine Learning, Deep Learning, and Cloud Computing. I bring a background in engineering, web development, and teaching, and am expanding my skills in data engineering tooling. When I'm not studying, working or learning something new, you can find me practicing yoga and participating on voluntary projects (aiming health: post covid breathing trauma, postpartum women, post-surgeries recovery and well being of patients with cancer).…I am an AI Data Specialist and Prompt Engineer with hands-on experience in LLM data annotation, evaluation, and prompt optimization.
