Java EE Contractor. Homeside Lending. July 2001 – November 2001

Homeside Lending is now Washington Mutual. I co-developed a J2EE-based loan tracking system to replace an overworked Microsoft Access application. The software monitored the status and location of various legal documents and tracked worker productivity. The environment consisted of IBM WebSphere 3.5, IBM VisualAge for Java 3.5.3 and Merant PVCS. The software discipline was J2EE (JSP & Servlets) with Microsoft SQL Server 6.5 and 7.0. Significant client-side Javascript was involved.

Unfortunately, the company experienced financial problems (here and here) and released many of its contract employees soon after. I was not able to finish the project.

Software Engineer. Nations Bank / Bank Of America. June 1998 – January 2000

The final segment of my bank employment lasted approximately 18 months. At that time, I was a Software Engineer helping to develop CreditWeb, an ASP-based web application for the bank's commercial credit centers. I had already built several websites, so my web development skills were beneficial to the project. The software replaced an aging Power Builder application. The environment included Windows 98 and NT, IIS, Visual Source Safe, Elsinore Technologies’ Visual Intercept, Dynalivery Parallel Crystal, Visual Interdev, Visual Basic, ODBC, SQL, and Sybase ASE.

Tasks:

  • Coded the “Total Credit Exposure” module of the application using ASP and Visual Basic.
  • Managed several IIS application servers
  • Implemented a service that allowed Crystal Reports to be rendered in parallel on a report server and sent to a client with minimal latency.

C++ Software Developer. Barnett Technologies. August 1996 – June 1998.

The middle segment of my banking experience lasted almost two years. I changed my career direction to software development. I was unseasoned, so this job really opened my eyes to making applications production-ready. I helped develop and support a 16-bit Windows application used by commercial credit customers. It let them perform various banking operations from their offices: stop pays, electronic funds transfers, balance inquiries, etc. The development environment was Windows 3.1 and 95, Borland C++, Booch Components, RogueWave zApp Studio, Install Shield, PVCS, Elsinore Technologies’ Visual Intercept, and the Btrieve database.

Market Information Officer. Barnett Banks, Inc. September 26, 1994 – August 1996.

The first segment of my banking experience lasted almost two years. Barnett Banks, Inc. was the holding company for the various legal entities that comprised Barnett Bank. It was also home to the company executives. I was employed as a Market Information Officer to help the bank do “whatever it takes” to keep Barnett in control of the Florida market. My previous market segmentation experience was a plus here. The technical environment was composed of Windows 3.1/95 and OS/2 workstations and a Novell Netware server. Programming environments included Borland C++, DB/2, SQL, Attachmate Extra, SQL, FOCUS, SPSS, Mainframe SAS, PC SAS, Borland Paradox, Microsoft Access, DataWatch Monarch, Data Junction, COBOL, and MapInfo.

  • Integrated statistical data into GIS software to produce data-bound maps
  • Designed, installed, and managed a 50-user Novell network

Computer Operations Manager. Humana Healthcare. February 1993 - September 23, 1994.

I was hired by Humana as a Software Developer because of my database experience. I worked with the Alpha Four database and created a tool which helped the company reclaim its overpayments to participating physicians 2). The system worked extremely well, resulting in a headcount reduction of 6 FTEs3).

I earned a promotion to Computer Operations Manager and became responsible for 3 employees, approximately 300 desktops, and a raised-floor data center consisting of AIX servers, optical storage units, UPSs, and a host of telephone equipment. I spent the next several months working with this equipment, plus bix blocks, punch-down tools, a small PBX, twisted-pair wiring, and Token Ring MAUs4) and CAUs5). It was a fantastic work experience, but I realized that my passion was software rather than hardware.

Research Associate. William Cook Advertising.

I conducted demographic research using Claritas's PRIZM market segmentation product. I used it to conduct database marketing campaigns. First, I found the right type and number of customers who were close to a store. Then, I purchased addresses on magnetic tape. Finally, I had them delivered to a local fulfillment house for printing, assembly, stuffing, and mailing.

I also used a desktop database called Alpha Four to manage my campaigns. We tracked our results via codes printed on the materials we mailed. Unfortunately, the agency lost its largest client (Winn Dixie) and many people had to be let go, myself included. Fortunately, I had a niche job and was the only one who could do it. I contracted with William Cook while job hunting, which worked out well for both of us.

Sales Associate. AC3 Computer Centers.

My second job after college was an attempt to get into the computer business. I didn't have enough experience to work as a software developer, but I could at least *sell* computers and be around the right people. This was a fantastic introduction to client management, sales leads, cold calling, and time management. I also received weeks and weeks of technical product training directly from Compaq, HP, Microsoft, and IBM. I used this time to improve my database skills (with DBase and Q&A), network skills (OS/2 Lan Manager and Novell Netware), and operating system knowledge (OS/2, Windows, AIX, and SCO Unix).

Engineered Product Salesman. Hub Inc.

My first job after college. I went through a 90-day introduction to the Pipe, Valve, and Fitting business while located in Atlanta. Fantastic exposure to metals and refining, manufacturing processes, products and their vendors. I was trained in Engineered Products (pneumatically controlled valves, measuring devices, etc…) because I enjoyed the physics and mechanics of it.

Even though the company had a computer for creating and storing quotes, it did not handle the work I needed to do: flow and volume calculations, matching of valves to actuators, calculating safety margins, etc..). So I found myself writing Lotus 1-2-3 macros to do calculations on my home computer. Ultimately, I learned a lot about chemistry, physics, metalurgy, manufacturing, fluid dynamics, and mechanical contracting. And I really began to see the benefits of custom software.

Pre-College Efforts

  • Built a memory expansion device for the Commodore VIC-20 computer. Mostly consisting of wiring and mechanical relays plugged into a double-sided breadboard. Allowed manual bank-switching between up to four 16KB memory cartridges, giving the computer a max of 67.5KB RAM. A whopping 19X improvement!
  • Wrote a small memory manager. Programs that used it would display a text message on screen telling the user to switch to a specific memory bank and press return.
  • Wrote a text-based adventure game similar to Dungeons and Dragons. Used my bank-switching memory manager. Random movement for all “monsters” in the game. Visual map of dungeon showing player's location.
  • Built a speech synthesizer from a phoneme chip purchased from Radio Shack. Required electronics knowledge, circuit layout skills, breadboard etching know-how, and good soldering skills.
  • Wrote software in machine language and BASIC to make the speech synthesizer work. The program stored the phoneme sequences for words, and sent instructions to the speech chip based on sentences entered at the command line. (Built in 1982!)
