Electronics Engineer with more than 15 years of experience. Most part of my career I have been working for a highly respected Swiss company SENIS AG. Since one year ago I am working only as a freelancer. I mostly worked on process automation tasks using different kind of NI and non NI equipment, such as Data Acquisition devices, Motion controllers etc. I also have huge experience with instrumentation control using various communication protocols. One of the most complex projects I have worked on is a SENIS Mapper device, operating the linear and rotational stages using the motion controller, while synchronizing the analog input acquisition with the encoder feedback.
