I'm a DevOps Engineer based in Brazil.
I love building developer tools, experimenting with AI and LLMs, and turning complex problems into simple, reliable solutions.
I'm passionate about infrastructure, automation, backend development, and everything in between. Always tinkering, learning, and building something new.
