Jan 2005 - present .::. Cylant, Inc., Lexington, MA USA • http://www.cylant.com

Cylant is a venture-backed startup company developing a product that monitors and protects software services running on Microsoft Windows Server SMP servers. The product works by learning the sequence of low-level service and resource requests made by software applications and alerting network administrators to changes in system runtime behavior that indicate malfunction, attack, or compromise of mission critical software resources. I am Cylant’s resident Windows internals expert responsible for the development of the kernel-mode routines that produce the raw runtime telemetry data consumed by the product’s analysis engine.

Sep 2004 - Dec 2004 .::. PREVX, Ltd., Milton Keynes, U.K. • http://www.prevx.com

PREVX is a privately-held security startup developing a Host Intrusion Detection system for Windows desktops. The product employs a policy-driven “filewall” that prevents malicious software from modifying critical system resources by filtering service requests in the OS kernel. However, the product is largely ineffective if deployed on a system that has already been compromised. PREVX hired me to assess this weakness and recommend a strategy that could be executed in discrete phases to incrementally improve their product. I architected and implemented means of automatic removal of malicious software packages.

Developed an extensible XML schema for describing malicious packages in terms of expressions, and delivered a collection of C++ classes that implements a custom framework for detecting and removing those malicious packages. Project applied Hyperworx routines to implement a “fly-by-XML” system - effectively an XML-driven, domain-specific, application server comprised of a graph splicing engine and an object factory.

Jan 2001 - Jun 2004 .::. Encapsule Systems, Inc, Yarmouth, ME USA • http://www.encapsule.com

I founded Encapsule Systems in 2001 to develop and commercialize an extensible visual programming platform called Hyperworx. Conceptually, Hyperworx is motivated by the observation that much of the cost and risk associated with developing complex software products can be eliminated by applying formal modeling and logic synthesis technologies from VLSI circuit design to software development. For more information on the Hyperworx Platform technology, please visit hyperworx.org.

One provisional patent filing on the runtime configuration mechanism. Functional prototype system completed (120K+ lines of C++ code). Support of the software as open source continuing as time permits.

May 2000 - Dec 2000 .::. J2 Interactive, Corp., Boston, MA USA • http://www.j2interactive.com

J2 Interactive provides a subscription-based interactive learning environment for children that includes games, puzzles, and highly filtered access to web, e-mail, and kid-to-kid chat rooms. I developed the low-level TCP/IP packet inspection / filtering subsystem that prevents the young users of this system from doing things on the Internet that their parents don’t approve of. This subsystem was delivered as a Windows 2000 / Windows XP device driver and DLL to make it simple for J2 to integrate the device driver into their Macromedia Flash-based client.

May 2000 - Dec 2000 .::. Polycom, Inc., Pleasanton, CA USA • http://www.polycom.com

Polycom is a leading supplier of high-performance hardware accelerated video / audio conferencing and remote collaboration systems for business. For this assignment, I was tasked with assessing the feasibility of porting Polycom’s DSP-based adaptive echo cancellation algorithms to Windows and incorporating the AEC directly into a USB audio device driver to eliminate the cost of a dedicated DSP in several peripheral devices. The results of this investigation were delivered as a written report, reference device driver, and simple Windows client application to affect control and status monitoring of the AEC subsystem at runtime.

Mar 1999 - Feb 2000 .::. Analog Devices, Inc., Norwood, MA USA • http://www.analog.com

Analog Devices is a leading supplier of analog, mixed signal, and digital signal processing semiconductors used in a wide range of devices. For this assignment, I wrote a software-based music synthesis subsystem that was bundled with ADI’s SoundMAX AC97 audio CODEC. This saved the expense of incorporating these features directly into the silicon. This software was delivered as a combination of a Windows device driver coupled with a Windows service for Windows NT and Windows 2000 and was bundled by PC OEM’s Toshiba, Dell, Gateway, IBM, HP, and Acer. Tens of millions of copies of this software were shipped without a single bug report.

Feb 1998 - Feb 1999 .::. Media 100, Inc., Marlboro, MA USA • http://www.media100.com

Media 100 develops and markets video editing, special effects, and DVD authoring systems for use in movie and television production facilities. I joined Media 100 to help develop their first product for the Windows Platform based on the ambitious 844/X Genesis engine (real-time special effects, and video compositing hardware accelerator comprising several custom PCI plug-in cards). I was originally hired to work on the Windows NT drivers required to interface the 844/X Genesis Engine hardware to Media 100's sophisticated UI software. However, the production of the hardware was delayed and I ended up working on resource allocation and scheduling algorithms required to maximize the utilization of the 844/X. As a postscript, Media 100 delivered their first product based on the 844/X Genesis Engine hardware in 2002 and won Best of Show at NAB.

Prior to being acquired by Polycom, Inc., PictureTel was a leading supplier of high-performance hardware accelerated video / audio conferencing and remote collaboration systems for business. I worked as part of their LiveLAN H.323 product team and was responsible for the audio transport, and overall installation of audio, video, and networking plug-and-play drivers for LiveLAN 3.0 - a hardware accelerated H.323 client for Windows 95 that won Network Computing Magazine’s Product of the Year honors in 1997 over competing products from Microsoft, and Intel.

The Hyperworx Platform Project

The Hyperworx Platform is a collection of technologies developed by Encapsule Systems, Inc. that comprise a system for designing and deploying custom software applications from visually represented specifications.

As time permits, I have been working to document this system and get the 100K+ lines of C++ source code published on SourceForge under the terms of the C++ Boost Software License.

The WTL Open Source Project

The Windows Template Library (WTL) is a C++ template library replacement for Microsoft's older MFC technology. In the six years since its quiet release, the WTL has quickly become the library of choice for developing low-overhead, high-performance native Windows UI's for scientific, financial, engineering, entertainment, and embedded Windows applications. (See also: The Code Project WTL Page).

In 2004, I was one of a handful of non-Microsoft employees invited by Microsoft to help administrate the WTL library as an open source project on SourceForge.

MIT Enterprise Forum of Cambridge

In 2001, and again in 2003 I presented the Encapsule Systems venture concept at the Forum's Concept Coaching Clinic - a useful learning experience for entrepreneurs.

Maine Software Developers Association

In 2003, I presented the technical details of designing software with the Hyperworx Platform's Software Circuit Description Language (SCDL) at the 11th Annual MESDA Conference.
