About Matias
I help engineering teams ship faster and sleep better at night. With 20+ years in IT and 10+ in DevOps, I specialize in AWS cloud infrastructure, IaC with Terraform, and building reliable CI/CD pipelines that actually scale.
I designed Feature Stacks — fully isolated AWS environments per feature branch, auto-provisioned via Terraform and integrated with Jira — eliminating squad conflicts and cutting staging costs significantly. I also led a zero-downtime EKS to ECS migration and solved a critical Aurora PostgreSQL performance problem on a table with hundreds of millions of rows using partitioning and S3 archival.
I work well both as a hands-on engineer and as a technical lead. I’ve managed distributed teams across Spain, the US and India, and I communicate clearly in English and Spanish.
Typical projects I take on: cloud migrations, IaC implementation from scratch, ECS/EKS containerization, CI/CD pipeline design, platform reliability improvements, and AWS cost optimization.
