I'm Lucas — a freelance Cloud DevOps Engineer, Site Reliability Engineer and Cloud Architect based in Hamburg. I help companies build, automate and operate enterprise-grade AWS and Azure platforms with Terraform, Kubernetes, CI/CD and modern observability.
Senior Cloud DevOps Engineer with proven success as Platform Owner for enterprise-wide AWS and Azure platforms (Tchibo, EnBW) and in migrating critical on-premises systems into the cloud. AWS Certified Solutions Architect Professional.
I focus on the parts of cloud that decide whether a platform actually works in production: clean Infrastructure-as-Code, fast and safe CI/CD, observability that catches issues before users do, and a security posture that holds up to enterprise scrutiny.
Past clients include E.ON, Mercedes-Benz Tech Innovation, EnBW, Tchibo, Audi/Volkswagen and the German Federal Employment Agency — across energy, automotive, retail/e-commerce, aviation and the public sector.
Two complementary engagement profiles. Often delivered together — a platform that's both well-architected and reliably operated.
Hands-on platform engineering. I build and run cloud infrastructure your developers actually want to use.
Strategic architecture for AWS and Azure landing zones, multi-account networks and cloud migrations.
