What I'm looking for

I'm focused on Cloud Operations and DevOps.

At Senior Sistemas S/A, I supported critical AWS and IBM Cloud environments, handling N2/N3 incidents and administering cloud resources. I developed Bash automation for updating customer systems, and the solution was maintained in production.

In my Gastos-App lab, I containerized a full-stack application and set up a staging environment on AWS EC2 with Docker Compose and Nginx. I also created a GitHub Actions CI pipeline for tests, linting, and builds; automated CD remains a planned next step.
