Freelancer Overview

I have experience with AI training tasks involving response evaluation, prompt analysis, data quality review, and comparative assessment of model outputs. I have worked on evaluating whether AI-generated responses follow instructions, meet quality expectations, handle technical requirements correctly, and provide accurate, useful, and well-structured answers. My background in software engineering, cybersecurity, and IT audit helps me review outputs with attention to detail, consistency, risk, correctness, and evidence-based reasoning. What sets me apart is my combination of technical knowledge and strong analytical judgment. I have experience with Python, JavaScript, backend systems, security controls, documentation, and structured quality assessment, which allows me to evaluate both general and technical AI responses effectively. I am fluent in Portuguese and English, so I can support multilingual AI training tasks, especially involving translation, localization, technical writing, and response quality evaluation across both languages.
