Avantgarde Labs GmbH
Back-end developer and application architect
In my largest assignment, I worked as application architect on an E-Commerce project, specifying and estimating the integration of new features as well as conceiving and documenting a Microservice-based target architecture. I interacted on a daily basis with requirements engineers and developers.
In addition, I worked as part of a development team on a handful of data-intensive projects using Scala, Java, graph databases and some of the more recent functional reactive technologies such as Akka and RxJava. Occasionally I was responsible for developing prototypes employing ETL tools, big data and search technology.

As a sideline, I conceive, design, develop and sell plug-ins for professional DAW software, targeted at performers and producers of electronic music. The main technologies I use for this purpose are React, RxJS, C++ 11, CMake, MSVC, RxCpp, VST SDK and REAPER SDK.
Additionally, I publish general-purpose open source libraries from time to time.
The results of my work are presented on my project website www.helgoboss.org.

Besides creating software, my main interest is composing and performing music. I have been playing the piano since my early childhood and had the privilege of enjoying a classical piano education for over 13 years. I won prices in multiple national piano competitions and played the keyboards in several bands as high school and university student.
In the last few years, I regularly performed live on the piano accompanying silent films with own compositions and improvisation. In 2015 I recorded the piano solo album "Shadow Paintings" with own compositions and compositions of guitar teacher Adam Lawson. It is available on here on Bandcamp.
