### {{< icon "calendar-alt" >}} 2018 - 202{{< icon "question" >}} {{< icon "building" >}} Komm.ONE as **SysOp** / **DevOps Engineer**
{{< icon " calendar-plus " > }} **2022** Cloud-Platform Infrastructure Project
Komm.ONE decided to create a complete new `Cloud-Platform Infrastructure` . The project started several years ago and replaced all software and hardware. Now it was our turn - So we started planning and implementing our test stage in the new environment. 2023 will challenge us to review and adapt the automation stack to changing requirements...
{{< icon " calendar-plus " > }} **2021** New Full Stack Self Service Portal
In 2021 I wanted to get back into coding and software architecture. So I started refactoring our Self Service Portal. The requirements have changed so much in the meantime that we decided to start from scratch. So we started a new full stack project containing these key elements:
| Tier | Components |
| ---- | ---------- |
| Backend | [Go ](https://go.dev/ ) + [Node.js ](https://nodejs.org/ ) |
| Frontend | [Vue.js 3 ](https://vuejs.org/ ) (with [Pinia ](https://pinia.vuejs.org/ ), [Vue Router ](https://router.vuejs.org/ )) & [Quasar ](https://quasar.dev/ ) |
| Data Management | CouchDB, MongoDB, SQL |
{{< icon " calendar-plus " > }} **2020** Cloud-Frontend Automation Stack
The year 2020 started with designing a new Automation Stack. My main goal war to upgrade the tech stack while
keeping the required operating an maintenance as low as possible. So I replaced some products to split the features / responsibilities:
| Role | Replaced Product | New Component |
| ---- | ---------------- | ------------- |
| Operational Platform | native Apps | Container based with [Docker ](https://www.docker.com/ ), [traefik ](https://traefik.io/traefik/ ), [Portainer ](https://www.portainer.io/ ) |
| Git VCS | Phabricator | [Gitea ](https://gitea.io ) |
| Artifact Store | Jenkins | [Nexus Repository Manager OSS ](https://www.sonatype.com/products/repository-oss-download ) |
| Build Server | Jenkins | [Drone.io ](https://www.drone.io/ ) |
| Wiki + KB | Phabricator | [Outline ](https://www.getoutline.com/ ) |
| Landing Page | Phabricator | [Ghost CMS ](https://ghost.org/ ) |
| Event Monitoring + Alerting | - | [Prometheus ](https://github.com/prometheus/prometheus ), [Alertmanager ](https://github.com/prometheus/alertmanager ), [cAdvisor ](https://github.com/google/cadvisor ), [Karma ](https://github.com/prymitive/karma ), [Grafana ](https://github.com/grafana/grafana ) |
| Service Status | - | [Uptime Kuma ](https://github.com/louislam/uptime-kuma ) |
| Web Analytics | matomo | [Umami ](https://github.com/umami-software/umami ) |
| Static Websites | Jenkins | [Hugo ](https://github.com/gohugoio/hugo ) |

{{< 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
2023-01-22 12:15:27 +01:00
business unit 4.2 _(Integration-, Security- & Application Management)_ . My previous team was reassigned to this new
2021-12-23 11:08:00 +01:00
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.
