I am responsible for the architecture, design, and operation of KfW's cloud and DevOps platforms, with a primary focus on Azure and GitLab in a highly regulated enterprise environment. My role spans cloud architecture, platform engineering, and DevOps governance, supporting multiple product and delivery teams. I lead the strategic migration from Azure DevOps to GitLab, defining target architectures, CI/CD standards, security controls, and operating models while ensuring stability of existing delivery pipelines and developer productivity.

A core responsibility is the end-to-end architecture and foundation of the HashiCorp Vault Enterprise platform. I designed and established a highly available Vault cluster on OpenShift, serving a hybrid and multi-cloud environment (on-premises and Azure), including secure integration with GitLab (JWT authentication for CI/CD) and OpenShift (Kubernetes authentication for workloads). AWS is used as a secondary / backup cloud, aligned with the overall cloud architecture and automation standards.

In addition, I act as a technical authority and trusted advisor, supporting architectural decisions, resolving complex platform issues, and continuously improving security, automation, and scalability across the cloud landscape.
