Hi there!

I'm a passionate software engineer from Hamburg, Germany, and in the business since 1998.

(To be exact my first IT job was when I fixed the computer of a car repair shop in my home town when I was a 13 years old boy.)

Between 2001 and 2019 I lead my own companies (arcus(x) GmbH, Brain, Cool & Schmidt and Avoid Murphy Products) and developed systems for several industry sectors:

  • Banking
  • Dating,
  • e-Commerce,
  • e-Learning,
  • Education,
  • Insurance,
  • Logistics,
  • Medical Research,
  • Publishing,
  • Shipbuilding,
  • Stock Exchange,
  • Travel,
  • Translation.

In the last years I was not happy with the contractor relationship anymore. I wanted to work as close to the product as possible.

Currently I am employed by a big retailer in Hamburg.

While most fluent in Java, Javascript, and Python I am also experienced with Go and many more programming and scripting languages.

I feel at home in the Frontend and in the Backend, have maintained infrastructure as code for several years and do operations as well.

I love simplicity, testing, k8s, docker, ansible, terraform, Linux, make, the command line, nodejs, Maven, the Spring framework, flyway, PostgreSQL, S3 and GCS, CockroachDB, Cloud Spanner, async messaging, React, DDD, CQRS/EDA, feature toggles, ... and going the extra mile to make customers happy.

I am opinionated about slowing down progress because of synchronous reviews and bullying developers with code metrics.

Currently I prefer working in the cloud (GCP & AWS), but I am also experienced with taming on premise infrastructures.

I have a strong foundation in isolating, modelling and implementing business logic. And I really know how to organize software to keep it maintainable for a long time.

Though I love building software from scratch, my heart beats for modernizing legacy systems.

OSS Projects

Because I love to share code, I have created some more or less successful projects:

OSS Contributions

I contribute to other OSS projects, such as:

Non-OSS Projects
