Maker of Fine Tools & Instruments

I work on implementing a hypertext system, which has also led to the development of various format conversion tools, automated processing workflows, interface designs, parsers/interpreters, viewers/editors, etc. Here I try to find synergistic projects and challenges that represent a chance for deploying + improving my solutions and techniques. Apart from that, I'm also a full-time employed software developer in the enterprise world. [login to view URL]

I could not have been luckier. Stephan knew I was anxious under a time crunch so he kept in steady contact with me throughout the short but intense development period.

Stephan is just perfect. He delivered the result in short time and in perfect condition, together with detailed installation instructions for me, so nothing could go wrong. I can strongly recommend him.
