I wrote (by myself) a complete real-time, multi-tasking operating system in Motorola 6809 that (even 25 years later) controls oil pipelines, ships, and refineries.
I wrote device drivers for VMS, did crash dump analysis... invented products for Ingres - and literally wrote the book on performance tuning the Ingres RDBMS. I led a large research team in UC Berkeley's ERL, founded three software companies ...
All that and I still love to write code.
Besides that, I'm a New Orleanian, a pilot, play trumpet, sculpt in metal...
