1990 - 1995 The Early/Mainframe Years
While working for Information Resources, I developed applications that delivered market research data to manufacturing clients (Coca Cola, Proctor & Gamble). The company was converting its systems environment from IBM mainframe to UNIX client server and I was part of the conversion team. This was my first opportunity to work on something other than mainframe development and it was invigorating.
Northern Trust was my first job out of college. It felt great to be out of school and working in the city. I was a COBOL/mainframe developer and member of a team responsible for maintaining an Electronic Funds Transfer (EFT) System. The system included COBOL CICS on-line and batch job processing. During this time I was on 24 hour support duty and carried a pager with me at all times. Pagers... those were the days. Sadly, Twitter was not available on pagers back then.
