From the classroom to architecture

I'm from Pernambuco, Brazil. I studied Mathematics and taught it before becoming a developer. The classroom taught me to explain complex things simply, and that's what I try to do with code: clear, documented systems that are easy to maintain.

Today I'm a software architect at ONR, helping teams set standards, integrate systems and clarify concepts day to day. Before that, at Apex NFT, I worked on Castles NFT, one of the most popular games on the WAX blockchain, and gave a talk on NFTs and crypto at SEBRAE's booth at Trakto Show.

I'm an open source enthusiast, which is why so many of my projects are local tools with no account and no cloud, that anyone can clone and run.
