Andreas Kleber Since June 2018 I am working as DevOps Engineer in the global DevOps Infrastructure Team at ESI Group. The main goal of our team is improving engineering efficency. My work focuses on automation and developing and maintaining the complete infrastructure stack and custom services for all development teams.

For 10 years before that I worked as Software Engineer at ESI Group with the focus on developing the immersive user interface of the Virtual Reality solution IC.IDO.

Accomplishments

The following lists some of my main accomplishements in the last 10 years (latest first) where I did the majority of the work in these projects. Often times I had experience with these systems before and do maintenance after the introduction or migration.

Setup of a new Conan Group for internal support and consulting.
Introduced and supported the usage of Windows and Linux Containers for CI builds.
Developed a new CMake base build system prototype for a large Fortran based product to replace legacy makefiles. Training the product team and handover. Motivation was to reduce build system copmlexity by removing the dependency to cygwin for the Windows builds.
Developed a new CMake based build system prototype for a product using Visual Studio project files and makefiles. The goal was to make the Linux version of the product a first class citizen and not an afterthought to the Windows version.
Support of the migration from Redmine to Jira as company wide modern issue tracker.
Migration of RTC Jazz repositories to Git with GitLab for code review and Jenkins for CI builds.
Setup and introduction of a Docker host for providing custom services out of containers.
Introduction and setup of a TICK Stack (mainly Telegraf and InfluxDB) for monitoring the shared build infrastructure.
Architecture, development and introduction of a shared build infrastructure for CI.
Developed and introduced Conan for dependency management with Artifactory for central binary hosting. The goal was to increase reusability of components between teams and streamline the process to provide binaries for all required platforms by creating a lightweigt Python and Jenkins based automation layer.
Merging of two Jira instances of two separate teams to reduce maintenance burden and license costs.
Maintenance of a team specific Confluence instance and introduction of Confluence to all developement teams.
Introduction of Puppet for automated build node setup (Windows and Linux).
Migration of a SVN repository to Git with Gerrit for code review and Jenkins for CI builds.

Education

In 2006 I finished my Diplom-Informatiker degree, studying at the Institute for Computational Visualistics at the University of Koblenz-Landau.

References

Here are some of my work results from my university time. They are a bit dated and technologically not really relevant anymore today, but I am nevertheless still proud of them.

2007: Filtering Video Volumes using the Graphics Hardware

The results of my Diploma Thesis were presented as "Filtering Video Volumes using the Graphics Hardware" by Matthias Biedermann and myself during a poster session at the "15th Scandinavian Conference on Image Analysis" (SCIA) in Aalborg, Denmark and in its proceedings.

2006: Diploma Thesis

In my Diploma Thesis "Erstellung eines Frameworks zur Filterung von Volumendaten auf der GPU am Beispiel von Videosequenzen" I investigated if modern GPUs (at the time) can be used to improve the speed of image processing algorithms on video sequences compared to CPUs.

2006: Touch-o-Mat

The Touch-o-Mat combined hard- and software into an innovative interaction metaphor for computers. Instead of using mouse and keyboard at a desktop, users stand around a table and are able to work intuitivly on the desktop with multiple fingers at once.
The Touch-o-Mat was built by Rodja Trappe and myself and won the audience award of the CV-Tag 2006.

2004: Grandma's attic

YouTube

This computer-animated short film, a sequel to Pixars Academy Award nominated short film "Luxo Jr.", was created during the summer semester break 2004 by a team of 14 students.
It won the "ANIMATION PRIZE OF THE PUBLIC" at Eurographics 2005 Conference in Dublin.
I created several of the digital 3D assets, did the final cut and produced a making-of documentary and the DVD.

2004: Virtual Marionette

The goal of this University project internship was to simulate realistic movement following a tracked (6DOF) physical input device with a beautiful rendering on a stereo projection system.
My tasks as lead of the integrated system was the development of the base system architecture and coordination with the physics and design leads.
The result was shown as "Lab-Presentation" at the IEEE VR 2005 Conference in Bonn.
