About me

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 came to Berlin in 2013, to work as a software developer. I have always been fascinated by "pure" data processing, so I first worked as a backend developer with Perl/Python or in the web crawling team. 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 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

For the implementation in the cloud I am up to date with the state of the art as Certified Kubernetes Administrator

My current topics of interest are:

• Data Engineering: Apache Airflow, Data Vault, ElasticSearch
• DevOps: Openshift, Kubernetes Development + Administration
• Full Stack Development: Flask, Streamlit
• Graphs: Graph Databases (Neo4J), Graph Visualization, Graph Representation Learning, Graph Algorithms (on Big Data)

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'm currently booked till end of 2024 and won't be fully available until Septemeber 2025.

Outside work, I am a chess player, enjoy hiking, volunteering at conferences, sporting events or as election workers and I enjoy visiting meetups.
Since Covid-19 changed the world I consistently use the bike and on weekends you can now usually find me on a longer tour around Berlin with the trekking bike and if there is enough free time I also use it for multi-day tours through Germany.
