Welcome. I’m Renato Guerra Cavalcanti, an independent software architect. My background is in distributed systems, Event Sourcing, CQRS, and Domain-Driven Design. What drives my work is design: code that is not only correct but sound, and the engineering practices that give software a strong foundation, whether a human or an AI writes it. This is where I publish my talks and write about design decisions, trade-offs, and what I learn along the way. Have a look around.
