2020 – present
Teaching, building and making sense of the field
Full-time official teaching delivered globally, and beside it advisory on the decisions that carry consequences.
In 2020, a career-long thread became the whole cloth. After two decades where teaching accompanied every role, training became the work itself: full-time, official, certified instruction delivered to professionals and teams across the world. The first year set the pace. Qualifying to teach an official course means attending it as a student, holding its certification, and then passing the instructor qualification; that year it was done six times, covering nine courses, followed by thirteen deliveries in thirty-three days, 264 hours in front of 51 students. What makes this era distinct is not just the focus, but the deliberate, dated expansion across platforms, each one added on top of deep practitioner experience rather than in place of it.
Full-time, by vocation
Since 2020, the work has been delivering official instructor-led training, remotely and in person, in Portuguese and English, to audiences around the globe. The delivery reaches Australia, Singapore, India, Central Europe, the United States, and Brazil. Brazilian and German citizenship, together with a valid United States visa, make that global reach practical: the right to travel, live and work across the European Union and wherever a German or a Brazilian passport is accepted without a visa, and the freedom to go where the classroom is.
F5, from the start
F5 has been the anchor since the beginning of this era, building on work with BIG-IP that reaches back over a decade. The authorized curriculum covers the full BIG-IP instructor-led catalog: Local Traffic Manager, DNS, Advanced WAF, Access Policy Manager, Advanced Firewall Manager, SSL Orchestrator, BIG-IQ, iRules development, automation, and troubleshooting, ranging from one-day to four-day courses. Alongside the teaching runs a practical complement: managed F5 BIG-IP lab environments, so that hands-on practice always has somewhere real to happen.
The expansion, platform by platform
What distinguishes recent years is a clear, dated progression. Extreme Networks training was added from 2021, covering EXOS switching, SD-WAN, and automation. Fortinet followed from 2024, centered on the FortiGate administration track (FCP at the time; NSE 4, FortiOS Administrator, since Fortinet reorganised the programme in July 2026). Netskope joined from 2025, covering Netskope Security Cloud operation, administration, implementation, and integration. Each platform was added deliberately, each resting on the same two decades of network and security implementation underneath.
Through Red Education, to the world
The primary vehicle for this global delivery is Red Education, an authorized training center through which official certified courses reach organizations across regions. The role is global technical training instructor, delivering to the kind of international audiences that a São Paulo base, two passports, and a genuine love of travel make possible. The standing relationship turns individual expertise into something organizations worldwide can book and rely on.
This is where the through-line of the whole history pays off. The curiosity of the early years became the implementation depth of the practitioner years, and that depth is now what every student receives: someone who built these systems explaining how they actually work, and why.
