Curriculum Vitae

August 1997-Present: Independant Software Consultant

In late 1997, I struck out completely on my own and have designed,implemented and deployed a large number of projects for a wide variety of clients.

• Developed the core technology for a start-up in Internet advertising inventory management. Developed the base architecture, the core mathematics, and the bulk of the core code from the original patent document.
• Architected, designed and headed the implementation of a new web-based CTI (Computer Telephony Integration) system for a large call-center. The server side is a stand-alone Java application running as a Windows Service. The server uses the Genesys CTI API to proxy call information. The client side consists of a Java applet and a Javascript/HTML presentation layer. The client also uses the Java Native Interface in an MFC/Telephony API (TAPI) DLL to communicate with the Lucent/Avaya Callmaster telephone set. This technology is in use on approximately two thousand agent desktops.
• Architected, designed and headed a three man team to develop a Web-based home automation system. Developed a standalone proxy server to handle communications with an Home Automation Incorporated controller. Developed several Servlets and Java Server Pages to handle requests.
• Developed a Linux daemon to run TCP/IP speed tests for a WISP. Developed several Perl robots to monitor network health and status. Also developed some management tools (JSP/Servlet) for selfsame WISP.
• Architected, designed and headed the development of a new factory automation system for a start-up company. This system has a distributable real-time event/data delivery capability, with an internal data/event driven expression language, and allows dynamic addition of new functionality to the running system. Designed from the ground up to run 7x24 at high data volumes, this system is currently deployed in several locations. The system is 100% pure Java and runs on both Windows and Linux platforms against SQL-Server and Oracle. It utilizes several technologies including RMI, Servlets, JSPs, JDBC, SOAP/xml, .NET and many others. It uses small embedded Windows (CE .NET) boxes at the factory machines to collect data and forward it to the server application using SOAP. The server (service or damon) receives data from the devices on the floor, performs various calculations (configurable via the expression language) on the data and forwards it to various monitoring and reporting systems in real time.
• Architected, designed and developed an all-new embedded controller for a laser cutting/engraving machine. The system was modeled in Rational Rose/UML and implemented in C++ utilizing the Wind River Tornado RTOS. The system features a hard, real-time PID servo loop, full graphical user interface, embedded Web server, handling for several TCP/IP-based application protocols, embedded trajectory generation for high order curves, and many other industry firsts.
• Headed a project team that developed a Java-based, distributable claims processing system. Did the bulk of the architecture and design work and guided the development of the system. The system featured a rules engine, run-time pluggable components and other advanced architectural ideas. The system was completely round-tripped through Rational Rose/UML, with all final code generation being done through the tool.
• Taught Object Oriented Analysis and Design, Object Oriented Design Patterns and various Java/C++ topics privately and through the University of Colorado Continuing Education Department.

August 1994-August 1997: Vice President and Software Consultant, The Stoker Group Inc.

Co-founded the Stoker Group Inc, a group of software consultants with a team/project orientation. Successfully negotiated the founding team's exit from employment at SCC. Did sales work including presentations and their preparation, negotiations and closings for about half ($1.8M total) of The Stoker Group's business. Worked with legal counsel to create the company's legal framework. Managed the bulk of the projects signed. Helped develop procedures for the safeguarding of the proprietary information of competing Stoker Group customers. Examples of client work:

• Did project management, database design and development for a new health care system which provides counseling to call-in clients.
• Developed a technology and protocol-neutral communications class library in MFC/C++. Did all object decomposition and implementation. Developed a Windows communications server/router for use in the customer's Computer Aided Dispatch System.
• Developed a Windows printer driver capable of mixed raster and vector output for a laser cutting and engraving system. Wrote some uniqe algorithms for polygon reassembly, color transformations and image scaling. Also developed a proprietary 3D rendering algorithm for emmulation of mechanical cutting/engraving tools on the laser. This algorithm set a new benchmark in the rubber stamp production industry, outperforming competitor's by a two-to-one margin.
• Did data and process modeling work and database design for a marketing system which included a large client contact database, an accounting system and remote communications capabilities.

May 1993-August 1994: Director/Development Manager, SCC Inc.

• Lead the development of a new Fire Records Management system, a large client server RDBMS system using a database engine neutral architecture. The system was developed with ACCESS, Visual Basic and Powerbuilder as the client tools and Erwin/ERX as the database modeling tool. The system contained multimedia capabilities for the storage of fire investigation photos and sound recordings on-line. Did much of the requirements analysis and data modeling. Developed advanced security mechanisms including a trapdoor algorithm for password encription and a Feistel network-based data encryption algorithm more secure than DES for the storage of sensitive data.

May 1991-May 1993: Senior Engineer, SCC Inc.

• Designed and implemented two major products that are part of SCC's flagship, computer-aided dispatch product. The first was a tactical information monitor built for Windows. Performed the analysis, object decompositions and product development. The product included a multi-protocol communications component, a tactical display configuration component, and a tactical information enunciator used to voice announce various significant events.
• The second was a set of interfaces to offload information from the CAD system in real time to various analysis and reporting tools. This product utilized Windows DDE to report to various Windows applications in real time and ODBC for database storage.
