- Designed and implemented a HTTP interface to the Worldspan travel reservation system. This interface is in use for a client that uses it to query for flights and hotel rooms, check inventory, and book tickets daily. The architecture includes a separate gateway web server that connects to Worldspan over either TCP/IP or a private X.25 line and translates between Worldspan commands and an internal application programming interface.

- Maintained ArsDigita's Oracle driver for the AOLserver web server.

- Implemented several AOLserver loadable modules for various projects, including ones to parse XML and to profile Tcl code.

- Technical lead on the Imago project, a production tracking system for animated feature films. The Imago system tracks work schedules and technical details of the animation process across the various departments involved in the production pipeline.

- Gathered user requirements, designed the database schema and application architecture for the web-based version that was used on PDI's feature films ANTZ and Shrek.

- Led the team of three programmers that re-implemented a Java-based version of the application suite that is currently in use.

- Developed a Python library and command-line scripts to access the tracking database.

- Installed Oracle 7 database server and served as part-time DBA.

- Developed vertical applications using NeXT's WebObjects dynamic web application development system and Enterprise Objects Framework (EOF), NeXT's object-oriented toolkit for integrating with relational databases.

- Wrote the SMTP delivery module for a company-wide distributed email application running under both NEXTSTEP and OPENSTEP for Windows NT.

- Lead engineer for the DriverKit object-oriented device driver framework. Designed and implemented support for the PCMCIA bus architecture and added support for EISA devices on HP-PA RISC computers. Developed an architecture-independent power management framework and implemented the Advanced Power Management BIOS driver for Intel-based computers.

- Had sole responsibility for the low-level OS booter for NEXTSTEP. Designed and implemented on-the-fly loading of device drivers. Made performance improvements to dramatically reduce OS loading time.

- Collaborated with the development tools group to deliver a dynamic shared library profiling tool. Designed and implemented the kernel side of the tool.

- Developed a SCSI device driver architecture for supporting multiple host adapters and peripherals.

- Wrote SCO's standard SCSI tape driver and worked with a customer to developer the QIC-40 minicartridge tape driver.

- Designed, developed and deployed the Spectre document management system for internal engineering documents.

- Performed general SCO UNIX kernel debugging and maintenance.
