Data Center Infrastructure Engineering for Telefonica Germany

Telefonica Germany's data center operations needed infrastructure lifecycle support from planning and build-out to expansion and ongoing operations. The work combined database-driven documentation, hardware support, and fault diagnosis.

My role covered the server landscape, fault diagnosis, and SLA-critical issue resolution. The database-supported documentation system made infrastructure status and performance metrics easier to inspect.
