I am an experienced DevOps professional with certifications including AZ-400, AZ-305, AZ-104, AWS SAA-C02, MCT (Microsoft Certified Trainer), and Terraform Associate.

I currently impact over 105 million users daily and facilitate transactions exceeding R$10 billion per month at the second-largest bank in Brazil.

I have hands-on experience in real production environments, addressing issues such as failed CI/CD scripts, pipeline fixes, workflow changes, troubleshooting Kubernetes clusters, and resolving complex network problems in APPGW.

Key highlights of my experience include:

• Solving complex Kubernetes issues, including modifying internal and external networks and ports, resolving context issues in .kube, fixing deployment errors (both app-related and deployment/resource-related), and addressing service errors.
• Resolving deployment failures caused by mismatched parameters in the CI/CD pipeline, ensuring smoother and more reliable builds.
• Improving Docker build performance with multi-stage builds and other optimizations.
• Troubleshooting network problems in Application Gateway, including: DNS, Load Balancer, TCP/IP/UDP networking and security, SSH and SSL connections.

My IT experience spans various industries, including banking, auditing, bots, and customer service. I also have FinOps experience, having saved over R$300,000 through cost-benefit optimization strategies.
