As a senior engineer on the R&D team delivering the company’s Linux-based VideoEdge Network Video Recorder:• Designed, implemented, and deployed a new client streaming architecture in C++ for delivering live and recorded audio/video from the NVR to security console workstation clients via RTSP/RTP. The new architecture implemented dynamic generation of video stream palettes offered to clients based on availability of local and remote transcoding resources, significantly surpassing the capabilities of competitors’ similar offerings.• Identified, coordinated, and executed OS migration tasks needed to move the VideoEdge NVR product from a custom in-house Linux platform to a commercial SuSE Linux Enterprise OS. Responsible for supporting new build environment, deployment and configuration management of developer tools, RPM packaging of Tyco and third party software, and delivery of final product disk images. The new platform relieved Tyco of much of the work for supporting OS security and bug fixes, allowing the engineering team to focus more on the video application suite.• Designed and developed C++ code to support command/control and streaming of video, audio, and text data from IP audio/video devices, Stretch audio/video capture PCI cards, and IP/serial Point-of-Sale terminals. Implemented a variety of GStreamer pipeline frameworks to support streaming in two versions of the VideoEdge device streaming architecture. http://www.americandynamics.net/Products/VideoEdge_NVR.aspx

As a senior developer working on the company's XMPP-based, real-time desktop collaboration product:• Designed, implemented, and tested a new Asterisk-based media server to support mixing, playing, and recording of conference audio. Created Asterisk dialplan applications, enhanced Asterisk open-source PBX core software as needed, and provided an XMLRPC API to access the audio services. The new media server greatly simplified customer acquisition and installation of Novell Conferencing.• Developed an audio test harness capable of generating thousands of outbound/inbound calls per hour to/from the conferencing system using Python.• Implemented enhancements to the Microsoft Windows and Linux conferencing client softphones, including: acoustic echo-cancellation, improved voice activity detection, and VoIP authentication/encryption.• Designed and executed evaluation tests and made recommendations for prospective software media server solutions that would replace a legacy hardware-based NMS telephony/media solution.• Implemented a custom authentication/authorization module for the Apache HTTP server to enable user access to conference recordings and whiteboard data stored on the conferencing web server.

As part of the development team responsible for Avaya's MeetingExchange suite of conferencing products:• Drafted specifications, designed, implemented, and tested audio processing software for the company's VoIP software media server. Maintained and refactored several key functions including RTP/UDP socket interfaces, audio jitter buffering, play/record, conference mixing, and automatic gain control. Added support for low-bitrate and wideband audio codecs (G.722, G.726, G.729, and iLBC). This server enabled the company to realize larger profit margins for their conferencing systems by eliminating the need to integrate third-party media servers.• Added ad-hoc conferencing features to Avaya's VoIP conferencing product in accordance with IETF SIPPING working group draft recommendations.• Designed and implemented software and firmware needed to enable “hot-swap” of T1 line cards in the TDM-based MeetingExchange product. Worked closely with hardware engineers to ensure integrity of the telephony bus during removal/insertion of cards. Identified and fixed bugs in card boot procedure.

As part of the team responsible for delivering new features for Alchemy, the company's Microsoft Windows-based IVR/CTI development and service platform:• Implemented call control and media processing using NMS Communications' NaturalAccess telephony stack.• Added support for speech recognition and text-to-speech in Alchemy applications by integrating Nuance Communications' ASR and TTS services into the platform.• Created speech recognition grammars and interactive dialogs for a Microsoft Speech Server-based application to enable voice access to Microsoft Exchange e-mail, calendar, and contact data.

As a developer helping deliver the company's automatic speech recognition (ASR) and text-to-speech (TTS) products, from startup through IPO:• Designed, developed and maintained core product software for high-density, telephone-based speech recognition systems on Windows NT and Unix hosts. Implemented endpoint detection and front-end acoustic processing algorithms on TMS320C30 DSPs, DSP resource allocation schemes, and host-to-DSP communication interfaces using serial and shared-memory I/O. This work directly supported the deployment of the first commercially viable telephone speech recognition systems for airline reservations and stock trading.• Integrated SpeechWorks’ ASR software with Dialogic's next-generation proprietary voice boards, cooperating closely with Dialogic engineers to develop a solution capable of replacing the DSP-based product and reducing continuing engineering costs.• Added support for the Media Resource Control Protocol (MRCP) to SpeechWorks’ server products, providing IETF standard-based access to ASR and TTS resources.• Added per-port licensing enforcement capabilities to the ASR and TTS server products.

Lead developer of DSP software for Excel’s programmable telephony switching platform.• Implemented algorithms for basic telephony signal processing, including: tone detection/generation, audio conference bridging, voice detection, and automatic gain control for TMS320C30 DSP processing modules.• Implemented resource allocation and IPC functionality needed to support DSP resources on embedded Motorola 68302-based systems running pSOS+.

• As a Systems Engineer, developed fire control algorithms for the US Army's Advanced Field Artillery System.• Edison Engineering Program: Completed graduate engineering degree concurrent with rotating work assignments developing underwater sonar simulation software, designing mixed analog/digital circuit modules for metering liquid gun propellant, and maintaining/upgrading naval missile test systems.
