Being into software development for more than 30 years now
— including 25 years of professional work for industry customers —
I had the chance to gather experience with different technologies and projects.
I do work free lance for various industry customers,
being responsible for design and development of complex software systems,
both hardware related real time software and applications.
Of course, software development does include problem analysis,
consulting and project management.
