I’m a retired I/T System Engineer whose 30+ year career included:

• Support and enhancement of the primary server farm for the U. S. House of Representatives

• Support and enhancement of the software development mainframe systems used to develop the on-board flight-control and complete, comprehensive system control of the Space Transport System (“Space Shuttle”) vehicles

• Various software development tasks ranging from applications development in (IBM VS) COBOL thru mainframe operating system maintenance and enhancement in IBM System 370 Macro/Basic Assembler Language to bash/zsh/Python shell scripting in the IBM AIX, Sun Microsystems Solaris (long may it shine in history), Apple macOS (Python only) environments

There were some odd stints along the way but I’m too old to remember all the details. Essentially I was a Jack of all Trades, Master of a Few.
