Software development has been my passion since the days of Windows 3.1. But even before that, there were already first trips into the world of the machine code. The handling of software would become my profession, but was not clear at the time.
In the early days there was just too little specific software. Especially in the database area, but in the commercial area, there was lack of good and affordable software as well.
THE “FIRST” CUSTOMER
My first customer asked me to write a cash book, which was tailored to his needs and should remain affordable. It was very successful for many years.
Around 1993, I started developing a key management for a bank. As a unique project, it developed over the years and decades to the key management TSKEY. The first version, still under Windows 3.1 was a great success. Over the years, many operating systems and architectures have changed, but TSKEY has always been up-to-date.
