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 also interested in:

• How to write a database management system in Rust
• GraphQL
• Enterprise computing (mainframes)

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 present time, I'm available.
