How I teach
An instructor who built these systems before teaching them.
Most technical training is delivered by people who learned the material to teach it. This is the opposite: three decades of building, breaking, and fixing real networks and security systems, distilled into training that connects every concept to how it actually behaves in production.
Why this matters in a classroom
There is a difference between explaining how a feature is supposed to work and explaining why it behaves the way it does at three in the morning when something critical is down. The first comes from a manual. The second comes from having been there. Since 1996, the work was implementation: designing networks, standing them up, and being the person called when they broke, for vendors and for some of the largest organizations in Brazil. That depth is what every student receives, not a presenter reading slides, but an engineer who has lived inside these systems explaining how they truly work.
Complex made clear
Deep technical knowledge is necessary but not sufficient. The rarer skill is translating it: taking something genuinely complex, web application firewalls, identity federation, traffic management, SD-WAN, and making it click for someone encountering it for the first time. Students consistently single out the real-world examples and the clear, structured didactics, the ability to put each concept in the context of the work they actually do. Teaching has been a thread through this entire career, present in nearly every role since 1997, and the full-time focus since 2020.
Hands-on, not hand-wavy
Technical skill is built by doing, not by watching. Every course is built around hands-on labs on real systems, reinforced with managed lab environments so that practice always has somewhere real to happen. The format adapts to the audience: virtual instructor-led training delivered globally, in-person when that serves better, in English or Portuguese. The goal of every session is the same, that participants leave able to do the thing, not just describe it.
Recognized, certified, and current
The teaching rests on a foundation of formal recognition. F5 DevCentral MVP for three consecutive years, in 2022, 2023, and 2024. F5 certifications held since 2015, and instructor authorization across four platforms: F5, Extreme Networks, Fortinet, and Netskope. Delivery reaches Australia, Singapore, India, Central Europe, the United States, and Brazil, through Red Education, an authorized training center. The credentials matter, but they are shorthand for the thing underneath: a genuine, current command of the technology.

Beyond the classroom
The same depth that makes for good teaching makes for good counsel. Thirty years across application delivery, network security, identity, and infrastructure, on both the vendor and the integrator side, with a consistent record of customer advocacy, is a perspective that travels well beyond a training room, into architecture decisions, technology selection, and the hard problems that do not fit a syllabus. The teaching is the focus; the experience behind it is available to teams that need more than a course.
Tools that compute, never guess
Alongside the training sits a growing set of free, privacy-first network and security tools, deterministic utilities that run entirely in your browser and never send your input anywhere. Subnet and CIDR math, IPv6, certificate and token inspection, and more, the kind of everyday tools a working engineer reaches for. They are built in the same spirit as the teaching: precise, practical, and genuinely useful. Try them, no sign-up, no tracking.
