About
My name is Lucas Barbosa Gomes, and I’m a DevOps/SRE/Platform Engineer — or whatever the next job title they come up with turns out to be, lol. I have nearly a decade of professional experience, specializing in cloud-native architectures and Kubernetes. I currently work as a Senior DevOps Engineer, focused on high availability, infrastructure automation, DevSecOps practices, and building scalable solutions to make developers’ lives easier. I hold the CKA (Certified Kubernetes Administrator), Azure Administrator Associate (AZ-104), and Azure DevOps Engineer Expert (AZ-400) certifications.
My journey
My path into tech started with technical courses — IT, computer assembly and maintenance, and later computer graphics. What pulled me in at first was the dream of making games (I was a hardcore gamer), but what really stuck was the curiosity to understand how things work under the hood.
I started my career while still in college, as an intern at a news portal, assembling newsletters in a fairly manual, repetitive job. That’s where I discovered what I actually enjoy: instead of repeating manual tasks, I started automating them, building tools, and provisioning environments. I spent 4 years there and learned a lot about development on a real product — it’s where I first worked with WordPress and where I built, the hard way, the habit of learning on my own. I eventually became responsible for the IT department, and that autonomy let me focus on exactly what interested me most: development, automation, and infrastructure.
At a WordPress-focused agency, my growth in DevOps practices accelerated a lot. That’s where I felt firsthand how important scalable solutions are, and the real cost of duplicated pipelines and repetitive processes. I deepened my knowledge of Cloud and IaC tools like Ansible and shell scripting, working alongside more developers and seeing operations at scale. There, I helped raise best practices for clients running that CMS to a high level of security and performance.
Then I joined a tech consultancy, where I deepened my work with Kubernetes and platform engineering in production — on-call rotation, incidents, and controlled changes — with responsibility for the GitLab CI/CD platform and production Kubernetes clusters (EKS and AKS).
I’ve also participated in the technical leadership of major migrations — from on-premises environments to cloud and from Kubernetes clusters to Azure — while evolving shared pipeline libraries, operational automation, and infrastructure as code with Terraform, Helm, ArgoCD, and Ansible.
About this blog
This blog is a space to document real experiences — what worked, what didn’t, and why. I write about DevOps, Kubernetes, Linux, cloud, automation, self-hosting, and everything that orbits the infrastructure and platform engineering world.
Most of what I’ve learned came less from courses and more from broken production environments, late-night incidents, outdated documentation, and hours staring at logs in a terminal. Since I learned to study on my own early on, I know how much it helps to find an honest account from someone who has already been through the problem. That’s what I try to bring here: real context, not Hello World tutorials.
I don’t write as a guru or as a tool evangelist. The goal is to share what I’ve learned — including the mistakes.
