About

I am a Computer Engineering student at Instituto Mauá de Tecnologia, focused on combining advanced analytics, robust software engineering, and business strategy.

Currently, I work in the AI and Advanced Analytics unit at Visagio (VLabs), developing Machine Learning, NLP and Generative AI models to solve complex operational challenges. By integrating computer science fundamentals and DevOps practices into my workflow, I ensure that the solutions I build are scalable and production-ready. My main goal is to translate raw data into strategic assets, optimizing processes and driving measurable value for large-scale clients.

I believe the most powerful AI systems go beyond technical complexity. They are designed to support executive decision-making, solve real-world business problems, and deliver direct impact.
