Capabilities

Solve tough programming and software design problems - especially problems that others have been unable to resolve.
Provide robust, cross-platform software solutions designed to last 30 years or more with minimal maintenance.
Develop, analyze and implement new algorithms to solve original problems.
Write accurate and consise technical reports and analyses.
Deliver clear, consise, and well-commented source code that is easy for others to read, understand and revise.
Provide staff training on a broad range of subjects including Software Development, Analysis of Algorithms, Programming Languages, Unix/Linux System Administration and Programming, and Networking.

Selected Recent Accomplishments

Designed and implemented a self-calibrating control and visualization program for an X-Ray defraction apparatus.
Designed, implemented, and demonstrated a prototype automated damage control system for U.S. Navy combat ships.
Implemented a Netscape Plugin from a commercial Motif widget under Solaris, HPUX and AIX.
Designed and implemented an HTML widget for Tcl/Tk. (Work in progress.)
Designed and implemented a specialized small-footprint web server to replace a commercial product for a cost savings of $100K.
Designed and implemented the client-server communications layer of an automated workflow management system for a national mortgage company.
Designed and implemented an SGML-based document generation and requirements tracking system for a large DoD re-engineering project.
Designed and implemented an event-driven programming language for an embedded industrial control system.
Designed and implemented a new 3-dimensional graphing widget for Tcl/Tk. http://www.hwaci.com/sw/plot3d/plot3d.html.
Extended Tcl (the Tool Control Language) to operate in a multi-threaded environment using POSIX threads. http://www.hwaci.com/sw/pttcl/pttcl.html.
Designed and implemented an X11-based graphical editor for an historical data-flow signal processing language. (A demo of this system can be arranged upon request.)
Designed an API that gives signal processing applications portability across symmetric multi-processors, traditional single-processor workstations, and special-purpose digital signal processing hardware.
Designed and implemented a compiler that converts an historical data-flow signal processing language into ANSI-C code.
Designed and implemented and object-oriented LALR(1) parser generator -- similar in concept to ``yacc'', but faster and with more capabilities.
Designed and implemented ``mktclapp'' -- a system that allows the Tcl/Tk GUI language to be freely intermixed with C or C++. See http://www.hwaci.com/sw/mktclapp/ for further information.
