Freelancer Overview

Experienced IT professional and AI training contributor with a strong foundation in computer science and system administration. I bring hands-on experience in evaluating AI model outputs, creating high-quality prompts, and contributing to projects focused on aligning models with human intent—most recently through my work on Project Sapphire with Pareto.AI. My technical skill set spans across Azure DevOps, virtualization, network monitoring, and enterprise infrastructure, which complements my growing expertise in AI data tasks. In addition to my technical acumen, I possess strong attention to detail and analytical thinking developed through roles in IT management and software development. I am fluent in English and have working proficiency in Portuguese and Spanish, allowing me to contribute effectively to multilingual data labeling and model evaluation projects. My goal is to bridge technical operations with AI development by delivering accurate, context-aware training data for robust model performance.
