At T-Systems, I provide L2/L3 production support for two concurrent applications, resolving 13–18 tickets per week and documenting root causes for recurring and high-severity incidents. I perform daily application health checks and monitor application logs, alerts, and performance using Dynatrace, Splunk, Kibana, and Grafana.
At Gallagher, I resolved live production issues, investigated application data issues, and participated in a 24/7 on-call rotation. I also led L2 documentation and supported scheduled patching and escalated-ticket resolution.
