  1. DevOps Engineer · CI&T

    Mar 2025 – Present · Belo Horizonte, Brazil

    I design, automate and operate AWS infrastructure: CI/CD, Infrastructure as Code, a Kubernetes-based observability platform and edge security.

    • Designed and maintained CI/CD pipelines with Azure DevOps Pipelines and Terraform to provision AWS infrastructure, cutting deployment time by ~47% and removing manual steps across multiple environments.
    • Built and operated an observability platform on AWS EKS (Grafana, Prometheus, Loki, Kafka, Alloy, Fluent Bit), improving incident detection time and monitoring coverage of critical systems.
    • Led the migration of the observability stack to another AWS region, rebuilding the EKS cluster and reducing downtime during failover scenarios.
    • Implemented AWS WAF from scratch, with custom rules to mitigate common web threats (OWASP Top 10).
    • Built Docker-based tooling, including Python sidecar containers for automation, log processing and custom metric collection.
