PROFESSIONAL EXPERIENCE

• Worked with a research team on the development of prototype engines for high performance XML instance validation and de-serialization based on XML Schema in Java and C to be used in web services and database applications.
• Developed a high-performance XML instance scanner in Java.
• Performance analysis of XML scanning/validation in the Java environment.
• Testing, bug fixing, and code maintenance in both the Java and C code bases.
• Reworked existing C code to make it more robust.

• Design and development of a Tcl language extension to support communications with Allen Bradley Programmable Ladder Controllers (PLC) over a network using the Rockwell Interchange DTL library. The extension is written in C and runs on Solaris 2.X and higher and HP-UX 10.x and higher.
• Design and development of an event driven application that communicates with multiple PLCs controlling the loading of palettes with finished product and passing the status and line data to a database application through a POSIX IPC queue mechanism. The application is fault tolerant and runs as a daemon. It is written in C and runs on Solaris and HP-UX.
• Development of an application that allows workers at a cereal packaging plant to configure the barcode printers at the palette loading stations. This is a graphical UI application that sends the selection to the database, which in turn sends the information to the printing stations. It is written in Tcl/Tk. This project also included the design and development of a product information editor used to maintain the list of selections available to the configuration program. This is also written in Tcl/Tk.
• Design and development of an application that monitors packaging machinery on a cereal packaging line for quality control and productivity statistics. The information is then passed on to a database to be used in automation control. This application is written in Tcl.
• Design and development of a Tcl package to handle communications with a network connected digital scale used in a cereal packaging line.

• Interface design and implementation of a web browser based point of sale system for the food service industry using the ASP (Application Service Provider) model utilizing JavaScript, XHTML, XML, XSLT, and CSS2 under Microsoft Windows Internet Explorer on the client side and XML, Perl, and Oracle DBMS with the Apache HTTP server under Linux on the server side.

• Documented and maintained existing code for various subsystems of a medical diagnostic device. Solaris 2.6, X11/Motif, and Oracle database running on an UltraSparc CPU for front-end, Solaris 2.6 running on a SuperSparc CPU for real-time and robotics control. Coding in C.

• Coding in C++ on Microsoft Windows NT as a part of a team developing a large metal buildings design, estimation, and ordering system for installation in field and sales offices of a metal buildings manufacturer. Microsoft Visual C++ 6.0.

• Documented and redesigned portions of client's application using C++ on Windows NT 4.0. The application consists of multiple programs, each running multiple threads, communicating via named pipes, semaphores and events.

• Developed concepts for delivery of multimedia game and educational titles over a limited bandwidth broadband connection. This involved dealing with extracting and assembling data packets embedded in the MPEG streams coming from the QAM demodulator (ISO Network Layer (3)) and dispatching the datagrams to the appropriate streams (ISO Session Layer (5)) that were used by the presentation engine hosted on the client set-top box.
• Developed prototype multimedia title engine in C++ for digital cable set top box using the PowerTV operating environment.

• Conceived, designed, implemented and deployed automated testing facility for message based Internet commerce systems providing both deterministic and non-deterministic testing paths, resulting in an 80% reduction in man-hours required for equivalent testing.
• Lead design of protocol and functional extensions to Internet payment system.
• Conceived and designed a system to allow tracking of individuals on the Internet and facilitating the delivery of MIME packaged information in a secure and timely fashion. This included communication directly between servers and clients (push), indirect communication via HTTP proxy (poll), and fallback via SMTP (e-mail).
• Developed and executed data migration, regression and load testing of Internet payment system server.
• Developed and implemented programs for MS Windows 3.1, MS Windows 95, and MS Windows NT to demonstrate a fundamental security flaw in most desktop operating systems.
• Analyzed and documented existing Internet commerce server code including functional decomposition, program flow and design issues, producing a 300 page HTML document. This reduced the time required to bring new staff to productive understanding by an estimated 50%-60%, as well as reducing maintenance time.
• Assisted in debugging and deployment on two major version transitions for the Internet commerce server systems.

• Chief architect, designer, and programmer of terminal emulation, graphics, and scripting core for MS DOS and MS Windows based terminal emulation products. Primary coding in C and C++. In this capacity, was directly involved with several products throughout the product life cycle, from concept through implementation, testing, release and maintenance.
• Involved in file transfer and user interface design and implementation for serial terminal emulation products.
• Designed and implemented core emulation engine for Digital ANSI and graphics terminals up to VT500 level for MS DOS, MS Windows, and Windows NT platforms, including:
  • ANSI Text
  • TEK 4014
  • ReGIS Graphics
  • SIXEL Graphics
• Designed and implemented IBM 3278/3279 terminal emulation for Microsoft Windows and Windows NT platforms.
• Implemented the graphics emulation portion of the Data General 470 terminal emulation product for MS Windows.
• Designed and implemented the Persoft Script Language for MS Windows based terminal emulation products.
• Wrote original end user documentation for the Persoft Script Language for the SmarTerm products.
• Designed and developed a suite of bitmap and outline fonts for terminal emulation on MS Windows platform.
• Responsible for creation and maintenance of terminal emulation reference model.
• Redesigned and rewrote emulation core of original MS DOS VT220 emulator, resulting in a code reduction of over 50%, substantially improving the accuracy of emulation and greatly increasing emulation speed.

• Developed and maintained a C language compiler, runtime library, and a suite of associated tools for a M68000 based platform.
• Assisted technical support staff with difficult customer problems, often dealing directly with customers.
• Produced example programs and detailed descriptions for product documentation.

• Terminal design, terminal and workstation firmware design and implementation, communication and protocol design. Coding in C, BLISS and assembly language on PDP-11, VAX, and M68000 platforms.
• Re-implemented graphics firmware components that reduced drawing time by a factor of 8.
• Designed and implemented NAPLPS and TELIDON graphics terminal emulations for PDP-11 based personal computer.
• Designed and led implementation of user interface, display list, and event driven real time operation kernel for embedded graphics terminal prototype. Implementation in C and 68000 assembly language.
• Designed extensions to ANSI and ReGIS presentation protocols for DEC serial terminals.
