Robin Carduner — Partner and Technical Lead

Robin brings nearly 30 years of software development experience to Cantus Firmus, having worked for Omicron Consulting, Syncro Technology Corporation, Thermo Fisher Scientific and others in the Philadelphia area, and for OSIsoft, LLC here in the East Bay. In addition to traditional desktop applications, Robin has worked with scientific and medical devices, embedded firmware, and various other environments.
