Matt T Heffron
Software Developer (Senior) Retired
United States United States
I started programming in Basic on a DECSystem-10 as a Freshman at Caltech in 1974. I quickly transitioned to assembly language, Fortran, and Pascal. As a summer job at JPL, I did analysis of fuel consumption for the Viking Mars Orbiter attitude control system. I also spent a summer doing O/S maintenance at Digital Equipment Corporation.
After graduation, I started developing microprocessor development tools (e.g., cross-compiler, debugger) for Beckman Instruments, a scientific instrument company.
I've worked on custom file-systems, a real-time O/S for Z8000, Expert Systems (SpinPro™ & PepPro™), and internal and external networking support (I was their first webmaster).
I've worked on the DNA analysis system.
I was the console/UI software architect for Ultracentrifuges and protein Capillary Electrophoresis (CE) systems.
After 35 years, Danaher having acquired Beckman (now Beckman Coulter), transferred the CE group to become part of Sciex (2014), and was on the software team that developed the new (9/2021) Sciex BioPhase Capillary Electrophoresis instrument.

Finally, after 43 years, 7 months, and 19 days, I am retired.
