Leonardo R.

I'm a DevOps engineer and SRE with 8 years of experience focusing on infrastructure automation and AWS cloud solutions. I acquired this experience by leading and participating in the development of the infrastructure for PIX, transforming Brazil's instant payment system. Additionally, I have a solid track record in cost analysis and reduction in high-availability environments for the financial sector, and in creating robust infrastructure for a large-scale mobile internet application. I was responsible for designing the architecture and executing the migration of a large-scale legacy mainframe to modern cloud architectures and microservices, improving operational efficiency, reducing downtime, and significantly saving costs. I have proven knowledge and experience with AWS, container orchestration using Kubernetes, Docker Swarm, Docker, and Helm, and in developing Infrastructure as Code (IaC) using Terraform, Terragrunt, CloudFormation, and Ansible. I have created CI/CD pipelines with Jenkins, GitLab-CI, and GitHub Actions, and done scripting with Python, Shell Script, and Golang. In the field of monitoring and observability, I have used Prometheus, Grafana, and New Relic to ensure the health of environments and resource optimization. Additionally, I use my experiences to analyze and optimize costs with tools like Harness and AWS Cost Explorer.
