I'm a full-stack software engineer with deep front-end expertise and over 9+ years of experience building production systems at scale. Throughout my career I've worked on platforms with 12M+ and 18M+ unique monthly users across different companies, including Zappos (an Amazon company), a company belonging to Itaú, one of the largest banks in Latin America, and companies in Australia and the United States, collaborating with global distributed teams. As a contractor via Tecla and OnChain Studios, I've also built web experiences for brands like Disney and Mattel. I'm currently pursuing a postgraduate degree in Artificial Intelligence, adding AI/ML knowledge to my background in JavaScript, React, data structures, algorithms, unit and integration testing, UX/UI design processes, and RESTful API design applied with agile methodologies. Outside of work, I love to travel and have had the pleasure of visiting countries like Argentina 🇦🇷, France 🇫🇷, the Netherlands 🇳🇱, Portugal 🇵🇹, and Spain 🇪🇸, as well as exploring many states across Brazil 🇧🇷, each place leaving me with a deep appreciation for its culture and beauty. I'm also an amateur musician: self-taught on electric guitar, acoustic guitar, bass, and drums. Music has always been a creative outlet for me. Above all, I cherish the time I get to spend with close friends and family.

I presented mypdfcv as a real example of building products with AI agents and MCPs across the entire development and production cycle. The talk covered RAG implementation, keeping AI costs under control, and pairing agents with product analytics so feature decisions come from data, not guesswork. Highlights from mypdfcv: 650+ resumes exported in a single month, reach across 67+ countries, and ChatGPT recommendations driving 2,637 visits, almost matching direct access. A reminder that AI can be both the build tool and the distribution channel.
