Back to original languageAbout Christian
👋🏻 Nice to meet you, I'm Christian.
Expert in Cloud and Kubernetes infrastructures with one obsession: to deliver a platform that works, grows with you, and doesn't give you a headache.
How?
By working hand-in-hand with your teams to design THE tailor-made hosting solution — not a generic one that will cost a fortune or crash at the first traffic spike.
🔍 Infrastructure Audit (the first one is free!)
-> We identify architectural problems, risks, and opportunities
🚀 Migration -> Scaleway, OVH, or AWS
-> We don't just move your infrastructure, we redesign it to be performant, scalable, and economical.
🎓 Kubernetes, Cloud, and CI/CD Training
-> I train your teams to understand, master, and become autonomous (people first).
Client Case: Unoptimized Kubernetes lift and shift migration, the client's production was running with only one pod per micro-service. We rethought everything and increased the number of replicas based on the service, which ultimately saved money because the previously empty nodes (DaemonSets + 1 pod) were not destroyed but still billed.
📩 A project? A question? A free audit to test?
