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
I work across different layers of technology — from infrastructure and security to systems, products and accessibility. Not as separate areas, but as parts of the same problem: making technology work reliably in the real world.
Through INIT4, I focus on security and compliance for companies in the audiovisual industry, especially within the TPN (Trusted Partner Network) framework. This involves everything from architecture and physical and technological infrastructure reviews to pentesting, observability and structuring processes to meet industry requirements.
With Sisteminhas, I take a different approach: I build and offer simple, straightforward and functional software. These are solutions designed to solve specific problems with minimal complexity — often offline-first, with no reliance on subscriptions or heavy infrastructure.
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.
