Professional and Technical Background

Although I had been tinkering with computer kits since the age of about 13, I first started programming in earnest on a Commodore CBM 750 in 1982. It was in Microsoft Basic, only had a 24×80 ascii screen (amber!), and we had to save our code on 8″ floppy disks; but I loved it!  I soon moved on to my first IBM AT running DR DOS and all it had to offer. My first Compaq Deskpro 286 was amazing for it’s time, no hard drive, but it had TWO 5.25″ floppy drives and was the envy of my peers. Although limited to BBS’s and Zodiac dial-ups, we were still able to dabble in the nescient Internet until CompuServe came along…


After taking all the programming and computer courses a high school advanced placement curriculum could offer, I began to take courses at the local community college while still in high school. After graduating high school I attended California State University at Fullerton, Computer Science. In additional to learning mainframe development and inverse ISAM indexing structures, Pascal, Fortran, C, and Assembly languages, I also continued to self-learn web technologies, HTML, TCP/IP and the new IBM technologies for the S/36: OCL, RPG II, and APPC/APPN SNA networking.

Early Career

During my sophomore year at CSUF I landed my first IT job as a graveyard shift computer operator with what is now Tenet Health Care (THC), but back then was NME. In our division of the company we had a network of thirteen IBM S/36’s scattered across the U.S. and one S/38 at corporate that were fed data from the hospital system’s garrison of 3090 mainframes via LU6.2 connections. Officially, my job was to run nightly backup tapes on the S/38, run 16 batch jobs on each of S/36’s via terminal Passthru, and contact the on-call programmer several times per night when these batch jobs would fail. Annoyed with all these “distractions” (and not knowing what a night operator was NOT supposed to do) I used my OCL and RPGII skills to rewrite the batch processes with error recovery and automated the whole shebang. Unfortunately, my boss noticed that I now had it pretty easy at night and promptly promoted me to the day shift.

As a day Operator, I wasn’t content with the defined duties of running batch jobs, printing reports, and stringing miles 5250 coax cable. In my spare time I soon re-configured the APPN/APPC SNADS network, replaced the existing point-to-point leased lines with an X.25 frame relay (MUX), and automated all backups. Having only been with the company for just under a year and still too new to be a “real” programmer (per company policy), a new position was created for me; Operations Programmer. In this role I was given leeway to develop and automate whatever operational tasks would give us the best bang for the buck. Over the next year I created a system to archive and restore reports to digital tape, a backup tape management and control system, and I scripted and coded an application that would perform the complete installation and conversion of all our S/36’s with new AS/400’s with no operator intervention other than to plug in the hardware. I also engineered and installed a 64 line Motorola modem nest for direct dial-up access to the midrange systems by the field staff spread out at all of the NME hospital facilities.  Soon after, I was promoted to Jr. Programmer in the Applications Development department.

Over the next 5 years, I was instrumental in a number of high profile projects with the company and was promoted through the positions of Programmer, Sr. Programmer Analyst, and ultimately Systems Architect where I directed teams of as many as 14 developers and as many as six concurrent projects. Through a referral from IBM to a specialty consulting group, I then made the decision to become an Independent Consultant. Through my own company, Firstsys, I have assisted many corporate clients achieve their goals in innovation, automation, and efficiency improvements.
