Technology Builder since 1996. Founder of INIT4 and creator of Sisteminhas.
The beginning
I started working with technology in 1996, when the web was still learning to walk. There were no frameworks, no YouTube tutorials, no Stack Overflow. There was documentation, experiments, and a lot of things breaking.
That's where I learned the first important lesson: systems that work are built by people who understand what can go wrong — before it happens.
What I do
Today I work at the intersection of three areas that are, in practice, the same thing: systems architecture, information security, and product strategy.
Through INIT4, I work with teams that need technical clarity — growing engineering teams, companies implementing critical systems, organizations that need to structure their security posture.
With Sisteminhas, I put into practice what I teach by building real products that people use — without shortcuts in the foundation.
Philosophy
Complexity is a bug, not a feature
Unnecessarily complex systems fail in unnecessarily expensive ways. The right architecture is the simplest one that solves the actual problem.
Security is foundation, not a layer
Added afterward, security costs ten times more and protects half as well. It needs to be present in architecture decisions from day one.
Documentation that outlives the team
Systems that don't document their decisions are systems that depend on specific people. That's a business risk, not just an engineering one.
Real experience beats theory
Books and certifications have value, but they don't replace years of systems breaking in production at 3am. That knowledge can't be learned in a course.
Technical consulting without the fluff
Teams that need architectural clarity, real security, and decisions that scale. No slides, no generic methodology.
