[{"content":"Welcome. I\u0026rsquo;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.

I\u0026rsquo;ve been writing software since 1999, and from the start I\u0026rsquo;ve paid attention to how software is designed, not just whether it runs. My work centers on distributed systems, Event Sourcing, CQRS, and Domain-Driven Design, and on the engineering practices that keep a codebase healthy: clean code, clear boundaries, and design that speaks for itself. I\u0026rsquo;ve built systems with Akka since 2013 and have contributed to it since 2017, first on the core libraries and most recently on the Akka Runtime and the Akka SDK. A Scala developer since 2009, I founded BeScala, the Belgian Scala User Group, and I speak regularly at Scala, Java, and broader developer conferences.\nOcto Cogito is the banner I think and work under. Whether on a team or alongside one, what I care about is helping people reason about the trade-offs underneath their code and stay in the driver\u0026rsquo;s seat as their software grows, especially now that AI can write the code but not make the judgment calls.\nThis site is where I publish my talks, write about engineering and the craft behind it, and share what I\u0026rsquo;m learning.\nA word on the name. \u0026lsquo;Octo\u0026rsquo; comes from my GitHub handle, @octonato, a blend of GitHub\u0026rsquo;s octocat and my own name. \u0026lsquo;Cogito\u0026rsquo; reaches back further, to my studies in philosophy and psychology, and to NeoCogito, the company in Paris where I started out as a developer. Put together, the name says what I care about: thinking before building. It is where I began, and how I think and work.\n","externalUrl":null,"permalink":"/about/","section":"","summary":"","title":"About","type":"page"},{"content":"","externalUrl":null,"permalink":"/authors/","section":"Authors","summary":"","title":"Authors","type":"authors"},{"content":"","externalUrl":null,"permalink":"/categories/","section":"Categories","summary":"","title":"Categories","type":"categories"},{"content":"","externalUrl":null,"permalink":"/series/","section":"Series","summary":"","title":"Series","type":"series"},{"content":"","externalUrl":null,"permalink":"/tags/","section":"Tags","summary":"","title":"Tags","type":"tags"}]
