Summary

Many years of experience building, operating and optimizing complex infrastructure and database systems with a focus on high availability, scalability and security - both on-premises and in the cloud (Azure, AWS). I have special expertise in automating deployments, monitoring infrastructures (e.g. Icinga2, Prometheus) as well as in migrating and managing the lifecycle of relational and NoSQL databases like Oracle, PostgreSQL, MySQL and MongoDB. I focus on regulated environments with requirements for compliance, availability and disaster recovery (BSI basic protection, ISO 27001, KRITIS).

As a generalist, I quickly understand customer needs and implement them independently. I combine forward planning, tactics and diplomatic skills to handle even major challenges with ease. My technical background helps me judge situations, decisions and their consequences.
