Worked with Hewlett-Packard to define a sales force automation system, and then designed and managed the implementation of the lead tracking system used by HP to distribute marketing leads to their sales force and to then follow each sales opportunity throughout its life cycle. The system was initially developed to use email as the lead distribution mechanism with a FoxPro database on the backend. The system has evolved to using the Internet as the lead presentation and distribution mechanism with Microsoft’s SQL Server serving as the database on the backend.

For a major supplier of fuel management systems to local and state governments, developed a Windows 3.1 based system to manage fuel depots. The first deployment was for the

County of Los Angeles. The system interfaced via dial-up modems with remote systems that controlled the dispensing of fuel. The system was developed as a Windows 3.1 application using C++ for the GUI and FoxPro as the database.

1983-1993 Member of team of developers that designed and implemented a system to gather performance data about fiber optic transmission systems for AT&T. This system provided the ability to gather data from remote sites, store the data in a custom database system, and generate reports. In addition, the system provided the ability to perform fault location in real time. This was an enhancement to the AT&T operations support system, TASC. This was written in C and HP Assembler for the HP1000 running RTE-4.

Member of development team responsible for designing and implementing the AT&T operation support system ACORN that performs alarm surveillance and control for small to medium size transmission networks. My portion of the project was the development of the command scheduler, which implemented the command language for ACORN. In addition, I developed the user commands used to perform telemetry diagnostics. I also developed the interface routines that allowed the users to use ksh as a programming language for developing user-implemented features. I was also responsible for developing aids to automate ACORN system testing. ACORN was written in C and developed on an AT&T 3b20 computer running ATT's UNIX System 5.2. ACORN runs on an AT&T 3b20 Model 400.
