Who I Am
About Me
Developer, Veteran, Builder
I'm a full-stack developer based in Belo Horizonte, Brazil with a background that bridges military logistics and modern software engineering. After 5 years in the U.S. Air Force supporting global operations across 24 countries, I transitioned into tech — and haven't looked back.
I specialize in building scalable back-end systems and polished front-end interfaces using Node.js, TypeScript, Vue, and React. Python is my go-to for automation, scripting, and AI projects — from inventory tracking in the military to building voice-enabled assistants with LLMs. At Clube Certo, I've architected microservices, payment integrations, and enterprise dashboards from the ground up.
