{{< icon "address-card" >}} Hi, my name is Marco Blessing and I live in the south of Germany near a city called
|
|
[Karlsruhe](https://goo.gl/maps/kDpo6bb9V2r).

## {{< 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" >}} **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 |
|
|
| ---- | ---------------- | ------------- |
|

{{< 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 Management)_. 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](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.
|
|
|
|
### {{< icon "calendar-alt" >}} 2008 - 2012 {{< icon "building" >}} Pforzheim municipal administration as **SysOp**
|
|
|
|
At the municipal administration of Pforzheim I was responsible for the **Software Packaging and Deployment**,
|
|
**MS-SQL Servers** and **Web Hosting**.
|
|
|
|
## {{< icon "graduation-cap" >}} Education
|
|
|
|
I successfully finished two undergraduate trainings as **IT Specialist For Application Development** and
|
|
**Management Assistant in IT-Systems**.
