Senior Product Architect

Tibco Software Inc.

Years in IT—

My first mainframe job—
Computer operator/programmer IBM 360/20 DOS. I worked at a shared hospital data center. Started out sorting massive amounts of cards feeding them into card readers and programmable card punches. Programmed in Autocoder, COBOL and Assembler. Databases were ISAM. Learned the art of writing efficient code to run in limited resource environments.

My favorite mainframe memory—
I worked as one of the product developers for the Official Airline Guides “electronic edition” in the early 1980s. This was the first public “online” airline information display and reservation system predating the Internet by many years. It would display the data in 24-line chunks like a teletype on your Commodore VIC-20, TRS-80 or IBM PC. It was considered state-of-the-art in the early 80s. Now I develop software products that transport billions of messages a minute across the globe. When I started working on the mainframe I would punch my programs on cards. Now I can work anywhere in the world using just my phone. The progress being made is amazing. My job as a commercial mainframe product designer and software developer is awesome.
