Consulting, planning and operation of IT infrastructure — from enterprise virtualization to self-hosted systems. Independent, solution-oriented, with a focus on sustainability and control over your own infrastructure.
From enterprise virtualization to container orchestration to sovereign infrastructure — end-to-end expertise from over a decade of hands-on experience in security-critical environments.
Planning, migration and operation of Citrix environments — Virtual Apps & Desktops, ADC/Netscaler, Provisioning Services. From technology evaluation through troubleshooting to operational handover. Experience from projects with several thousand users in federal agencies, automotive and healthcare.
Kubernetes clusters on bare-metal servers, CI/CD pipelines, microservice development with Java and Spring Boot. Highly available database clusters with Patroni/PostgreSQL. No cloud provider required — the infrastructure belongs to the customer.
Building and operating infrastructure on dedicated hardware — without cloud dependency. Own Certificate Authority, hardened Linux systems, firewall concepts, monitoring. For organizations that want to maintain control over their data and systems.
Not theoretical knowledge — everything proven in production. From kernel to application.
Beyond consulting, I am committed to open infrastructure and digital sovereignty in Europe.
An open protocol for EUDI-based identity, authorized communication and digital legacy. Federated, self-hosted, without cloud dependency. The technical infrastructure for ROND runs on my own bare-metal environment — the same expertise that flows into consulting work.
