Hi, I'm Gustavo πŸ‘‹

πŸ§‘β€πŸ’» Senior DevOps Engineer with a strong foundation in systems administration, evolving into cloud-native technologies, platform engineering, and distributed systems.


πŸš€ About Me

πŸŽ“ My journey began with a degree in Computer Networks, building a solid background in infrastructure, Linux, and networking. Over time, I transitioned into DevOps and SRE, focusing on automation, scalability, and reliability.

πŸ”₯ I have extensive experience in production environments, handling incident response, troubleshooting complex issues, and ensuring high availability of critical systems. I thrive in fast-paced environments, balancing incident management, documentation, and continuous improvement.

☁️ Today, I design and operate cloud-native platforms across multi-cloud environments. I have strong expertise in Kubernetes ecosystems (OpenShift, OKD, Rancher, EKS, OKE), Infrastructure as Code with Terraform, and GitOps practices.

πŸ” I have hands-on experience implementing GitOps workflows using ArgoCD, enabling declarative deployments, improving consistency, auditability, and rollback strategies.

πŸ… I also bring solid experience in AWS and Google Cloud (GCP), supported by certifications. I have worked with core services such as VPC, IAM, compute, containers, storage, and event-driven architectures, applying best practices for scalability, security, and cost optimization.

🐧 My SysAdmin background provides strong expertise in Linux, networking, DNS, storage, web servers, virtualization, and monitoring.

πŸ”„ I have led Kubernetes migrations (e.g., OpenShift to OKD), troubleshooting workloads and ensuring stable transitions. I also implemented Rancher to centralize multi-cluster management, improving governance and RBAC.

🎯 I am driven by DevOps and SRE principles, focusing on automation, GitOps, reliability, and continuous delivery.
