Developed and sustained software for the Media Processing Server (MPS), a multimedia interactive voice and response (IVR) platform for Customer Engagement and Transaction Processing Applications using proprietary and standards-based communications protocols. Wrote software for MPS components running on Solaris, Windows, and embedded operating systems.

Implemented signaling protocols to connect the MPS IVR to voice and data networks worldwide. Designed programming interfaces for telephony signaling services and developed value-added call-handling and data-processing applications. Designed product upgrades, and led teams to deliver them.

Maintained ISDN and DPNSS signaling protocol software for the MPS’s predecessor, the VPS/is. Added support for new regional signaling variants and tested compliance with published standards. Re-engineered VPS/is ISDN and SS7 protocols for inclusion on the next-generation IVR product.

Developed software for real-time military and commercial applications, including an embedded microprocessor-based controller for a TOW wire-guided missile gunnery training system, and a PC-based controller and image frame buffer for a medical imaging camera.
