Network Engineering Tech Manager at one of Brazil's largest fintechs. 20+ years connecting on-premise networks to the cloud — and now connecting people, leading high-performance teams under mission-critical pressure.
About me
I'm a network engineer by training, and today I manage a network engineering team at one of Brazil's largest fintechs. Along the way I learned that resolving a network incident at 3am and leading people under pressure are the same exercise at heart: understand the system, stay calm, act with method.
I started in on-premise networking — cabling, routing, datacenter — and followed infrastructure's natural drift toward the cloud. Today I move between AWS, Azure, OCI and GCP as naturally as I once talked about VLANs and BGP, and I'm increasingly investing in Infrastructure as Code as a way to scale all of it.
This site is a place to record that journey: behind-the-scenes of traditional networking and cloud, lessons from leading technical teams in mission-critical environments, and what I'm currently studying — from CCNP to AWS Solutions Architect Professional and CKA — with new posts every week.
What I write about
Five interfaces, one operator. Each section of the blog covers a front of my day-to-day as an engineer and manager.
Networking
Traditional networking and datacenter life: routing, switching, troubleshooting, and the lessons only production operations can teach.
Cloud
Multi-cloud network architecture, migration, and the behind-the-scenes of running critical infrastructure on AWS, Azure, OCI and GCP.
IaC
Infrastructure as Code applied to networking: what I'm studying, testing, and getting wrong on the way to the CKA.
Leadership
How to lead high-performance technical teams in mission-critical environments, without losing people or SLAs along the way.
Innovation
Ideas and experiments that bring network engineering closer to a more modern way of building and operating infrastructure.
IaC projects
Repositories with the Infrastructure as Code projects I've been building and testing.
Posts
A new post every week on networking, cloud, IaC, leadership and innovation — written with a light touch, backed by real day-to-day experience.
