EMPLOYMENT HISTORY
Dotclick Corporation (www.dmn.com)
June 2000 - February 2002
Chief Architect/Inventor
Designed a fully redundant, highly available, professional music web site using PHP, Linux, PostgreSQL, Oracle, Solaris, and various custom and 3rd party application servers. Designed database replication scheme for PostgreSQL which also serves as a differential backup. Designed and implemented a digital music identification system, a cornerstone to the company strategy. The music ID application server runs on Linux (or other UNIX) and is a high availability service which uses both multiple processes and threads. The Music ID system is based on an advanced text search / phrase recognition system I designed and own (FTSS) and tightly integrated with PostgreSQL. Designed and implemented a statistical recommendations system which analyzes a user's song history and recommends new songs which they may like, based on PostgreSQL. Worked with marketing on technical issues. Worked with operations on hardware selection and deployment. Designed database extensions to provide new features while reducing operational load. Designed search and recognition algorithms and programs to match various disparate music databases. Using MPI and clustering techniques, the process for database matching works across many systems. Advised and assisted Windows developers on operating system issues regarding the operation of the Dotclick plugin. Reason for leaving: Dotclick was unable to acquire funding.
Fast Search and Transfer (FAST)
October 1999 - June 2000
Senior Software Engineer
Fast Search and Transfer is an Internet search engine company. I was hired to interface with customers and design search solutions based on specifications. Customers to date include Lycos, Albert in, PAX, and CISP. Challenges of search engine technology are largely shear volume of data ranging in the terabyte range. Constructed a Linux cluster of 20 machines to design and test radically different ways of deploying FAST's product.

(independent consulting)
Mohawk Software is my own consulting company. It has numerous clients including ADAC, Dragon Systems, Dome Imaging, Wilmington Research and Development, and Servolift Eastern.
Contributor to the PostgreSQL project. Contributor to the PHP project. Designed and implemented high speed session management system for web server clusters (msession). Designed and implemented a high speed text search engine (FTSS) intended to create full text indexes of SQL databases. On a standard desktop x86 machine it can search 3 million records in approximately .03 seconds. Performance tests have measured a sustained 82 full text look-ups a second on a Dual PIII 600. Currently being sold as a product.
Other projects: Have submitted bug reports to various open source development communities. Beta tested Linux 2.2 and 2.4 kernels. Consulted with Dragon Systems to provide an "expert opinion" on the state and condition of a product about to be released. Designed NT kernel/application high speed communications interface. Wrote a persistent storage library that worked on both Windows and UNIX (Linux). Wrote series of Informix/CGI/DICOM interface programs for use on a Sun Ultra for a major medical supplier. Ported a Web/DICOM server based on Windows NT IIS and Microsoft SQL to Linux using PostgreSQL. Wrote emulated hardware cursor for a multi-head Windows NT display driver.
Dome Imaging, Waltham, MA
October 1996 - July 1998
Principal Software Engineer
Came in to replace Windows NT driver engineer in last months of project, a multi-headed Windows NT 4.0 video driver. In first two months re-wrote and re-designed key portions of driver key to Windows NT 4.0 functionality. Worked with customers, on the Beta program, to resolve issues created by DirectDraw on a multi-headed driver.
Tracked down and debugged low-level bugs in the video controller chip's manufacturer's reference code. Debugged kernel fault in video driver due to the implementation of MMX code in graphics acceleration.
Designed a high speed HTTP/DICOM server using TCP/IP. The code designed for this system works on both UNIX and Windows NT. On NT the code uses IIS and on UNIX uses Apache. Server project was based on a multitude of technologies, including Java, CGI Scripting, SQL, HTML, high-speed image manipulation. Designed a cross-platform class library of low-level abstracts to facilitate porting to other platforms.
Keithley Metrabyte, Taunton, MA
November 1995 - October 1996
Principal Software Engineer/Project Leader
Designed and implemented Windows 95 and Windows NT kernel mode library for Metrabyte's hardware product line. The kernel mode library allowed developers with minimal knowledge of VxDs and NT drivers to produce, from common source, both a Windows 95 VxD and a Windows NT kernel mode driver. Managed the next generation Keithley Metrabyte driver development, using my library as a base. Although Metrabyte was dissolved, some divisions of Keithley are still using this library.
Polaroid Corp., Cambridge, MA
June 1995 - November 1995 (Contractor)
Software Engineer
Worked on a long running product for Polaroid's image correction software product, Prism. Prism is an image analysis module that is to be shipped within Polaroid's many electronic imaging systems. Wrote image correction software for Polaroid's Electronic Still Camera that works on both Windows 95 (16 bit and 32 bit) and the Apple Macintosh. This software included a very fast median filter, a tunable edge detection algorithm used to enhance an existing pixel interpolation algorithm, and an object-based LUT-Matrix-LUT (LUT is short for Look Up Table).
