{{< 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](https://vuejs.org/) for
|
|
|
|
|
visualizing product changelog and configuration details. Therefore I had to relearn javaScript and started working
|
|
|
|
|
with the [materialize-css](https://materializecss.com/) 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**
|
2021-12-23 11:08:00 +01:00
|
|
|
|
|
|
|
|
{{< 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](https://www.phacility.com/phabricator/) as a developer
|
|
|
|
|
framework in combination with [Jenkins](https://jenkins.io/) 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](https://www.kivbf.de). 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](http://www.zabbix.com/). Unfortunately I couldn't find any extension to
|
|
|
|
|
monitor out IBM tape library or TSM data itself. So I developed own interfaces therefore.
