About

Hi, I’m Guilherme Nogueira — a technology professional focused on Cloud, SRE, DevOps and infrastructure.

I work with AWS, Kubernetes, Terraform, automation, observability, CI/CD, security, governance and the architecture of scalable environments. In my day-to-day, I help development, data and product teams run platforms that are more reliable, secure and efficient — from operational reliability and cloud cost optimization to monitoring and continuous improvement of infrastructure.

Beyond the technical side, I enjoy turning complex problems into simpler, well-documented and sustainable solutions — always looking for the balance between performance, security, cost and ease of operation.

What I write here

This blog is where I register real-world lessons from building and operating infrastructure. Expect posts about:

Cloud & AWS (multi-account, governance, cost)
SRE & reliability (incidents, observability, on-call)
Kubernetes & platform engineering
Terraform & infrastructure as code
Automation and the messy realities of production

No theory-from-a-course content — just things I actually run into and figure out.

The opinions expressed here are my own and do not represent my employer.
