During getting my PhD in physics and mathematics, I was stumbling into computers and software development. Starting programming with desktop computers in the 70-ties, and later using Fortran, Pascal, Basic, Assembler and C. Jumped to C++ in the 80-ties, and to Web technologies in the 90-ties. The applications ranged from offline programming of robots to banking software written in Smalltalk.

After 16 years working for Siemens, I got a master degree in renewable energy and was working for a company developing large redox-flow batteries used for integrating renewable energy into the grid.

Just having fun gaining experience…
