Work

Hi, I'm Niels — a freelancing software developer based in Hamburg, Germany.

I like to keep Linux servers happy and healthy, but primarily develop specialized applications according to the business needs of my clients. These range from scalable backend services over DIN/ISO compliant laboratory software to firmware for embedded IoT devices. Furthermore, the creation of websites for small to medium-sized businesses is also part of my skill set.

In recent years I worked with various clients, including the following:
