Andreas Sahlbach

Software Architect

I am software architect, technical lead and senior developer. My passion are reliable and scalable backend systems and their interfaces. I have over 20 year experience in software development and designed the last 15 years distributed enterprise systems.

My languages of choice are Java, Swift and C++ in Unix environments. I have a lot of experience with several open source frameworks and even contributed to some of them.

As a teamworker I enjoy development in an agile environment. In my current role as Java Developer at Volkswagen, our team follows the principles of Extreme Programming (Test Driven Development, Ping-Pong-Pairing).
