Freelancer Overview

With a background in recruitment, journalism, and AI-assisted tooling, I combine strong written judgment with hands-on experience in data quality and evaluation. As a Tech Talent Scout, I built an LLM-based candidate matching system, working directly with structured data, scoring criteria, and model output validation — core skills for AI training data tasks. My four years as a technology and science journalist at ZAP Notícias further refined my ability to assess accuracy, clarity, and context across large volumes of content, making me well-suited for annotation, content classification, and response evaluation work.
