Hi there! I'm Douglas, an Infrastructure and DevOps engineer. I'm currently the engineer responsible for the cloud-native architecture of a healthtech platform on Kubernetes (EKS) on AWS — from networking to disaster recovery, everything as code in Terraform. Before that, I spent years as a full-stack developer, which shapes how I think about infrastructure: always starting from what slows down (or speeds up) the people shipping software every day.

DevOps Architect  ...

Infinity Doctors
  • I designed and built, from scratch as the engineer responsible for infrastructure, the platform's complete architecture on Kubernetes (EKS) on AWS — frontends, queues, networking, backups, and a disaster recovery account — with 100% of the infrastructure versioned in Terraform.
  • I implemented AWS IAM Identity Center as the single plane of identity, federating SSO with Datadog, GitHub, and SonarQube.
  • I built CI/CD pipelines in GitHub Actions integrated with a self-hosted SonarQube instance running on the EKS cluster itself.
  • I migrated the EKS cluster's traffic routing from Ingress NGINX to Kubernetes Gateway API, standardizing service exposure via Terraform.
  • I led AWS account consolidation and workload migration as a cost optimization initiative.
  • I conducted a pre-pentest security hardening exercise, identifying real vulnerabilities in the environments before an external pentest.
