Experience
2012 - 20 KIVBF as SysOp / DevOps Engineer
2015 In 2015 I started automating several platform and workload related use cases. Unfortunately it’s closed source, so I can’t talk about details. But to give a glimpse at the underlining technologies I can notice they were based on Microsoft, VMware and Citrix products.
2014 As the automation team got bigger and bigger, we needed to define standards. That’s why I began using Phabricator as a developer framework in combination with Jenkins to build our modules. This enabled us doing code review, lint tests, unit test and building our own CI Environment.
2013 I joined into a new team which was building our new cloud infrastructure. We purposed to offer our customers IaaS, PaaS, SaaS and EaaS services. My focus shifted to automation and cloud orchestration. Back then I started using Powershell.
2012 I needed to get away from those wacky enterprise applications which were used in the public sector. So I took the chance to work in much bigger datacenter at KIVBF. There I ran the backup and restore solution called IBM Tivoli Storage Manager (TSM).
It was a great place to get to know such large environment and I finally started automating again. At this time I implemented the monitoring system Zabbix. Unfortunately I couldn’t find any extension to monitor out IBM tape library or TSM data itself. So I developed own interfaces therefore.
2008 - 2012 Pforzheim municipal administration as SysOp
At the municipal administration of Pforzheim I was responsible for theSoftware Packaging and Deployment, MS-SQL Servers and Web Hosting.
Education
I successfully finished two undergraduate trainings as IT Specialist For Application Development and Management Assistant in IT-Systems.
