About Tim

I’m a Cloud & DevSecOps Architect with 16+ years of experience designing secure, scalable cloud platforms for clients in energy, finance, insurance, mechanical engineering, and aviation. As Managing Partner at Jongerius & Partner IT Consulting, I combine hands-on delivery with technical leadership and strategic consulting.

One of my key contributions is the development of KubeStack, a production-ready Kubernetes delivery and operations framework enabling scalable, secure, and observable platforms across enterprise environments.

I specialize in platform engineering, security automation, and multi-cloud DevSecOps, with a strong track record in leading critical transformations — including the Azure DevOps → GitLab migration at KfW and the design of a microservice-based global IIoT platform on AWS EKS at Schenck Process.

In recent years, my focus has expanded to AI-enabled cloud platforms, including the secure integration of AI-assisted developer workflows into regulated enterprise environments. This includes designing cloud-native architectures for AI workloads, integrating services such as AWS Bedrock and Azure AI, and establishing governance, security, and cost controls for AI at scale.

Clients value my ability to connect deep technical execution with business outcomes, long-term stability, and scalable architecture.

    November 2022 - Today (3 years and 7 months)
    Frankfurt am Main, Germany
    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.
