Summary

I have over two decades of experience in software and hardware development, specializing in signal processing, TCP/IP networking and embedded systems.

Specific skills and experience

My skills include software design and development though complete life cycle, on Windows and Unix/Linux systems, including GUI and device drivers, DSP code development on general purpose and DSP processors, embedded development on DSP processors and microprocessors, analog and digital design with discrete and programmable devices, advanced multi-protocol web applications and project management and team leadership.

Languages

C/C++, Visual Studio/MFC/.NET, Java, Perl, TCL/TK, JavaScript, MATLAB/Simulink, SQL

Experience

2006-2007 Sr. Software Engineer, Adaptive Optics Associates, Cambridge, Massachusetts

I developed software in C, C++, .NET, and TCL to interface with cameras and mirror actuators for optical control systems. I improved and organized the TCL scripts used in prototype development, and the C code used in the operational systems. I implemented network control interfaces and programs to run these systems remotely.

2005-2006 Consultant (Firmware, Hardware), AMETEK Corporation, Wilmington, Massachusetts

I wrote test software and debugged a newly designed board connecting legacy aircraft engine signals to ARINC 429, based on the TI TMS320F2812 processor. I also designed an ATE fixture for testing the system using DxDesigner and PADs for PC board design, and helped debug the LabView control program.

2005-2006 Consultant (Software, Firmware, Hardware), XRF Corporation, Somerville, Massachusetts

For XRF Corporation, I designed and implemented the hardware and firmware for a control panel based on the TI MSP430. I also wrote and maintain a MFC application to connect their X-ray spectrometer to a PC, and aid their engineering effort by reviewing designs and maintaining a CVS SCM system.

2001-2005 Consultant (DSP, Software, Hardware), TechOnLine, Bedford, Massachusetts

1999-2001 Development Engineer, TechOnLine, Bedford, Massachusetts

TechOnLine is a web site specializing in delivering educational content for the hardware engineering community, with emphasis on DSP and embedded systems. I designed, implemented and maintained systems for TechOnLine users to run applications, such as processor development systems, over the Internet via their browser (VirtuaLab). These systems use Citrix Metaframe, Tarantella, server-based MFC/C++, Java, Perl, VBScript, SQL7 and PHP, and client-side Java and JavaScript.

I set up various microprocessor development systems to run on the VirtuaLab. The microprocessors included the Motorola/Freescale PowerPC, ColdFire and i.MX21, the Hitachi/Renesas R8, M16, and SH series, the TI 320C6000, the Analog Devices ADSP-BF533 and Oki ARM ML67Q5003. Software IDEs included CodeWarrior, Code Composer, ARM RealView, Embedded Linux, MATLAB, LabView, and Xilinx ISE. I developed hardware and user interface applications in Java, C++/MFC and .NET for the remote hardware access system, and device interfaces for Windows and Linux in C to access the hardware.

I also helped develop the engineering course content, and maintain the course delivery infrastructure, which used RealAudio, JavaScript and Perl. I wrote a Java applet and servlet to tunnel the Citrix protocol through firewalls via HTTP, and implemented remote interfaces to the servers via HTTP and SOAP.

1997-1999 Lernout and Hauspie Speech and Language, Burlington, Massachusetts

(Acquired Kurzweil Applied Intelligence)

1985-1997 Kurzweil Applied Intelligence, Waltham, Massachusetts

1994-1999 Project Manager, audio front end

1991-1994 Principal Engineer, audio front end

1988-1991 Principal Engineer, recognition software development

1985-1988 Senior Hardware Engineer

At L&H, I designed and managed the front-end speech processing software, as well as helping to design the COM-based speech recognition modules to fit in the Microsoft SAPI framework. I made the speech recognition engine multi-threaded to avoid starving the time-critical processing, and supervised re-writing the DSP code in object-oriented C++.

As Project Manager at Kurzweil, I managed a project that replaced our propriety DSP audio input board with standard sound boards, by re-hosting algorithms in C and assembly language to various DSP processors, and to general purpose CPUs. Ultimately the product, a large vocabulary speech recognition system, ran both with and without DSP processor, on the Windows NT, Windows 95, Windows 3.1 and Solaris operating systems. I also lead the implementation of ClearCase in the Kurzweil AI development environment.

As Principal Engineer on the front end, I was responsible for the audio input hardware and DSP algorithms running on the TI 320C25 DSP processor. I developed the event-driven architecture used with Windows and UNIX operating systems in the product, and implemented device drivers and interfaces for Windows NT, Windows, various DOS extenders, various UNIX systems, and TCP/IP. I designed and implemented the hardware and Solaris driver for a DSP board for the Sun Sbus. I also developed and maintained the audio data collection system used for QA and research, and was the technical contact for an Internet connection via NEARNet.

As Principal Engineer on recognition software development, I managed the design and implementation of the speech recognition algorithms for a large vocabulary speech recognition system running on a 386 platform. I was responsible for the organization of the software using an enhanced SCCS system running on UNIX.

As Hardware Engineer, I designed a DSP board for the PC, based on the TI 320C25 DSP processor, and gate array and programmed logic implementations of pattern-matching algorithms.

1979-1985 BBN Computer/Communications Company, Cambridge, Massachusetts

1984-1985 Group Leader in Hardware Development

1979-1984 Systems Engineer

I developed processor, memory and interface hardware for the Pluribus multiprocessor and C/30 micro-programmable computer used as routers. I also developed and debugged other hardware, such as a 68000-based bit-mapped terminal, and a bit-slice data encryption (DES) board used in network security systems (VPN).

While primarily a hardware engineer, I also wrote diagnostics and application programs in C, 68000 assembly language and microcode for network routers and security systems using TCP/IP.
