Primary architect for Proton Therapy Machines control systems, specifically the one at LLUMC. Primarily a C and C++ developer for the embedded/realtime control systems on Unix and Unix like systems ( started at BSD 4.1 - the real one that only UC campuses got to use) for 29 years. SunOS/Solaris/Linux Admin from '88 to '96ish - still have a hand in, but not day to day. Numerous worthless software patents (my opinion, not that of my employer). And most unusually - been with the same company since '88.
