about me

Professional Skills

PROBLEM SOLVER

I can quickly analyze, evaluate and solve a variety of problems independent of their level of abstraction due to my broad scientific training.

Project Manager

I’m experienced in organizing projects, instructing co-workers, talking to authorities and customers as well as presenting in front of large audiences.

Scientific Multilinguist

I can discuss subject-specific details with professionals from multiple scientific areas thanks to my interdisciplinary studies in IT, physics, chemistry and biology.

Software Developer

I can cover a wide range of  problems with my profound programming skills, most prominently the development of HPC applications, GUIs and daily routine scripts.

System Administrator

I can plan, setup, maintain and orchestrate linux/unix-based IT infrastructures including workstations, PC pools, fileservers as well as entire HPC clusters.

Typograph

I can typeset scientific and commercial related content into standard documents, presentations and posters using LaTeX, TikZ, Inkscape and Gimp.

tutorials

During the COVID-19 crisis I took some time to review and update my IT security concepts and decided to revive some of the tutorials and how-tos from my old page. I use them mostly for my own reference, but maybe they can be helpful to you as well.

New tutorials will be “unlocked” step-by-step. As “corona-special”, I start with a Jitsi Meet installation guide.

  • Elementary commands
  • …more coming soon…

  • coming soon…
  • Creating PGP key pairs using GPG
  • Creating SSH key pairs
  • Arch Linux @ Encrypted ZFS-Root

Tools I use on a daily basis that suck less 😉

coming soon…

  • coming soon…
  • Server monitoring with simple tools
  • Ansible in practice
  • Job scheduling with Slurm
