{{< icon "heart" >}} Favorite Topics
I'm very interested in PowerShell, NodeJS, Go and Software Engineering in general.
Additionally I love building CI/CD Stacks with different open-source products to spread the word of DevOps and Containerization.

{{< icon "calendar-alt" >}} 2018 - 202{{< icon "question" >}} {{< icon "building" >}} Komm.ONE as SysOp / DevOps Engineer
{{< icon "calendar-plus" >}} 2019 Internal Self Service Portal
I spent the second half of the year creating a single-page application based on Vue.js for visualizing product changelog and configuration details. Therefore I had to relearn javaScript and started working with the materialize-css framework and other well known node modules.
{{< icon "calendar-plus" >}} 2019 Release Management Tool MkII
First part of the year I was focused on expanding the Release Management tools and workflows for our cloud hosted applications:
- Added automated aggregation of release details for each hosted application.
- Added changelog workflow for documenting releases.
- Defined rollout life cycle states for each new release.
- ITIL compliant syncing of the release data into centralized CMDB.
{{< icon "calendar-plus" >}} 2018 KIVBF merged with its partners to form Komm.ONE in order to be able to offer uniform services. After adjusting the internal organizational structure, I'm now part of the business unit 4.2 (Integration-, Security- & Application Managent). My previous team was reassigned to this new unit as well, and was renamed into CAFS (Cloud- & Application-Frontend-Services). So my range of tasks changed slightly.
{{< icon "calendar-alt" >}} 2012 - 2018 {{< icon "building" >}} KIVBF as SysOp / DevOps Engineer
{{< icon "calendar-plus" >}} 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.
{{< icon "calendar-plus" >}} 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.
{{< icon "calendar-plus" >}} 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.
{{< icon "calendar-plus" >}} 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.
{{< icon "calendar-alt" >}} 2008 - 2012 {{< icon "building" >}} Pforzheim municipal administration as SysOp
