Principal Software Engineer working in the Bay Architecture Lab, supported various telephony products including switches and VoIP gateways using various protocols (SIP, Megaco, H.225) implemented on TI DSP’s with code written in C/C++.*Designed and developed FAX jitter-buffering system for T.38 real-time FAX over IP to improve resilience to network jitter.*Developed jitter-buffering system for real-time Voice over IP (VoIP) running VxWorks, which provided correct sequencing of out-of-band tone signaling (RFC 2833). *Developed FAX Class 2 interface and functionality, which was integrated into a Motorola DSP based MODEM with only a FAX Class 1 interface. *Contributed the development of an internal reusable library of Voice, FAX, and MODEM functions to reduce royalty payments and increase the ability of corporate products to interact.

As a Principal Software Engineer, supported CircuitSentry product which consisted of an embedded PC and several DSP based plug in cards as part of the FAA LINCS project. Implemented in C on TI DSP’s and Intel 80x86 running ROM DOS.Supported SmartCircuits add-on project for CircuitSentry - (data acquisition and control). This functionality involved the addition of an entirely separate access system utilizing PPP, SNMP, CHAP, DHCP and alarm messages sent to a different Network Control Center. Supported CircuitSelector – TI DSP based eight-to-one telephone line multiplexer implemented in C and assembly.Supported Telephone Quality Measurement System (TQMS) – Embedded PC with TI DSP based telephony card t. Implemented in C and assembly for the DSP and Windows 3.11 on the PC.Specific examples of roles and responsibilities:Project Engineer for CircuitSentry responsible for technical interface with customer.Project Manager/Engineer for SmartCircuits responsible for complete product life cycle including requirements collection and analysis and development of system architecture.Provided Engineering support for marketing on many customer visits.Lead Software engineer for CircuitSelectorMentored junior software engineersDeveloped test plansDesigned test and calibration fixturesInstituted configuration management and version controlDebugged systems using a variety of techniques and tools including: In-Circuit-Emulators, JTAG emulators, logic analyzers, oscilloscopes, serial ports, GPIO ports/pins, and intuitionDesigned and developed FAX testing capability and play/record interfaceDeveloped E&M signaling capability for Telephone Quality Measurement System

Penril DataComm Networks (1990 - 1993)As a Principal Software Engineer, supported multiple MODEM products and the 6000 series Network Management system. Products consisted of embedded microcontrollers such as Intel 8051 and Motorola 68302, and TI DSP’s including C31 and C52 with code written in C and/or assembly.Substantially modified and integrated purchased software components resulting in the implementation of FAX functionality including both Class 1 and Class 2 command interfaces in V.32 MODEMs. Implemented a proprietary error-correcting/data-compression protocol utilized on a side channel, which provided non-intrusive support for the Network Management system. Architected “Backhoe Circuit” handshake/synchronization protocol. Produced ‘make’ files and custom link command files to match customer specific software configurations with various hardware platformsIntroduced improved software methodology including coding standards (style guides) and a software version control system.

As a Software Analyst, he supported 3000 and 4000 series dot matrix printer products. Products contained embedded processors including Intel 8085, 8086, and 80186 with code written in assembly and/or C.Specialized in addition of optional features such as downloadable fonts, Over-sized characters, barcodes and other customer specific modificationsOptimized printer system code for speed and size to meet throughput requirements and system constraints.
