About me

Growing up as teenager with Turbo Pascal and Assembler, I studied computer science/mathematics at the FSU Jena and the Fernuni Hagen. Later I was active in the Perl community for some time. After doing something completely different for a long time, I moved to Berlin in 2013, to work as a software developer with a fascination on "pure" data processing, Starting with back development with Perl/Python and web crawling, continuing with full stack development, I then decided that I wanted to enter the world of very large amounts of data and familiarized myself with data science, machine learning, cloud computing and DevOps.

Freelancing

Since November 2019 I work as a freelance data scientist and can take care of the complete development process following the best practices of DevOps of a modern software solution onprem or in the cloud, with or without AI part:

• Data analysis
• Design and implementation of machine learning models including test-driven development and deployment on the desired cloud infrastructure or on-premise
• Data engineering including cloud computing and backend development (Python/Scala)
• DevOps with Terraform, Ansible, GitOps, AWS, GCP, Kubernetes or OpenShift
• on request incl. full stack development (Python/Django/Javascript/Perl)
• in any case in test driven way with a focus on security and data protection

Particular strengths

• All rounder out of the box: Through diverse experience, I cover a wide range of programming languages, techniques, tools and abstraction levels at a reasonable level from the 90s to the hot buzzwords of today
• Debugging: This enables me to recognize relatively quickly, systematically and purposefully why something is not working, even in an environment I am not very familiar with.
• Help and improve your team members: With great patience, I can look after team members individually, solve technical problems together and systematically help them to improve. The preferred method is pair programming.

Currently, I'm interested in my spare time, how to write a database management system in Rust.

Details about my professional career can be found on my LinkedIn profile or Xing profile. Of course I also have a Github account.

Please contact me if I can help you with one of my topics.

At the present time, I allow myself some free time, and would accept some small gigs. I will be fully available again in fall 2025.
