Summary

Many years of experience in building, running, and optimizing complex infrastructure and database systems with a focus on high availability, scalability, and security - both in on-premise environments and in the cloud (Azure, AWS). Strong expertise in automating deployments, monitoring infrastructures (e.g. Icinga2, Prometheus), as well as in the migration and lifecycle management of relational and NoSQL databases such as Oracle, PostgreSQL, MySQL, and MongoDB. Main focus in regulated environments with requirements for compliance, availability, and disaster recovery (BSI baseline protection, ISO 27001, KRITIS).

As a generalist, I quickly identify the customer's requirements and implement them on my own responsibility. In doing so, I combine forward-looking planning, tact, and diplomatic action to handle even major challenges with confidence. My technical background helps me assess situations, decisions, and their consequences.
