I was the sole person managing the entire platform – about 400 VMs and 20+ applications across multiple cloud providers.

• Multi-Datacenter Cloud Infrastructure: Designed and deployed OpenStack across 4 European datacenters (CSCS, Juelich, CINECA, BSC)
• PaaS for Project Partners: Installed OpenShift clusters with GitLab and Docker registry so teams could deploy their own applications
• Full Platform Ownership: Infrastructure design, application deployment, monitoring – the whole thing
