I'm a Senior Developer Relations & Software Engineer with 10+ years of experience, passionate about Web3, blockchain, and building scalable systems that real developers depend on. With an M.S. in Computer Science from UFPE (Deep Metric Learning for texture similarity), I specialize in dApp development, educational content creation, and community engagement. It`s about bridging deep technical work with the people who use it.

My path spans biometrics and computer vision research, enterprise API architecture at one of Brazil's largest telcos, and Web3 protocol engineering across multiple ecosystems. I'm always eager to take on new challenges and share what I learn along the way.
