Context

A regulated fintech payment platform with strong availability and compliance constraints.

Problem

A legacy OpenShift setup: high operational complexity and rising platform cost.

Solution

Workloads migrated to Kubernetes, delivered with GitOps (ArgoCD), Helm and Terraform, with an improved cluster security posture and standardised deployment workflows.

Outcome

About 300k€ per year saved, faster delivery cycles, and a simpler, standard Kubernetes operating model that the team could actually reason about.
