EXPERIENCE

HHH Tempering Resources Inc. Vancouver Wa. (May 2014 to Sept. 2016) Designed, developed and maintained an embedded software application for the control of large glass tempering furnaces. This software application features a classic model view controller focused on real time control over many digital and analog IO ports. The software package also includes a simulator and a builder with graphical interfaces for allowing easy configuration and customization of the furnace control software. All software was written in C# using Visual Studio. I was the sole software engineer at this company and my duties also included performing routing IT work, development and deployment of a number of software support tools such as automated backup systems, repositories, and the deployment of a number of servers (web, email, ftp etc.) on a Linux system. I was laid off in Sept. 2016 because the company decided to stop manufacturing tempering furnaces in the U.S. and sell furnaces manufactured in China instead.

WebCriteria Inc. Portland, Ore. (Jan 2000 to Dec 2001)) Joined this startup company and worked on the design and development of software agents used to analyze and rate the complexity of performing a given task on a set of web sites. Worked in an Agile programming environment using extreme/paired programming methodologies. I worked on server side applications using Java, and OCAML (a functional modeling language) to extend MAX. MAX is a robotic modeling agent that is at the heart of the technology used at WebCriteria to model a web site. I also wrote servlets and Java GUIs to work with a factory design pattern to help automate much of the process of performing a task analysis on a web site. I was laid off from WebCriteria in April 2001 when the company downsized by 40% of its workforce.

Tektronix Inc. Beaverton, Ore. (Jun 1995 to Jan 2000) In 1995, Tek labs were closed, and I joined one of the principal business divisions, working on the design and development of oscilloscopes. Initially, I was responsible for the continued development of the GPIB/SCPI parser-generators, and the integration of these software products into the TDS (Tektronix Digital Oscilloscope) oscilloscope product line. Subsequently, I was the principal engineer responsible for the Math and Measurement subsystems of the TDS family of oscilloscopes. I was also the principal designer and developer of a mathematical expression compiler. This compiler lets the user of an oscilloscope specify mathematical expressions for combining digitally sampled signals and integrating these with other measurements and digital filters that an oscilloscope is capable of performing. This embedded compiler generates code from these expressions, and inserts this code into the real-time data acquisition, processing and display subsystems of a digital oscilloscope.

Tektronix Inc. Beaverton, Ore. (Jan 1989 to Jun 1995) Initially joined the computer research labs and worked there for five years, researching, designing, and developing reusable software components for use on all products developed throughout the company. My major accomplishments included the design and development of a C++ cloner for use in embedded systems, and I was the principal designer, lead engineer, and project leader involved in the design and development of two different reusable parser-generators. These parser-generators were highly successful, and are used on all instruments developed by Tektronix. They control the GPIB/SCPI communications interfaces between different instruments and their controllers.

Olle Lindblad Konsult, A.B. Stockholm, Sweden. (Jan 1986‑ Dec 1988) I joined a consulting team which contracted my services for both in-house software development, and as a. consultant to Ericsons, a large Sweden based telephone company. Projects included the design and development of advanced debugging software for a network of Ericson's 68000 based systems (APN s), which could trace the causes of system crashes by maintaining a trace of signals and messages sent and received either between processes or across the network, process and memory allocation and deallocation requests etc. In conjunction with this project, I developed a specialized compiler which produced debug oriented code that was then inserted into Ericson's Pascal software and allowed the inspection of various process parameters in a real-time environment Additionally, was contracted to work on another Ericsons project which had fallen seriously behind schedule. This project involved an air traffic control simulator based around a network of 27 of the above mentioned APN's. Here I joined a special integration team and was responsible for the integration of Ericsons's real-time operating system with the various parts of the application software and hardware.

W.S.M. Group. Tucson Az. (Jan 1985‑ Dec 1985) Assisted in the development of a Unix like operating system and developed a Basic Interpreter for a 68000 base graphics system, developed by Commodore/ Amiga. This interpreter used some advanced techniques based on dynamic grammars and a Forth language based reverse-polish notation, and produced threaded tokenized code to give it a high runtime execution speed; being only approximately 10% slower than most compiled versions of Basic.

Multiple Mirror Telescope Observatory Tucson Az. (March 1981‑ Dec 1984) Located in southern Arizona, the Multiple Mirror Telescope is a. revolutionary new instrument design concept employing 6 separate telescopes housed in a single structure. Using computerized control, these telescopes were combined together to make the MMT function as the worlds largest aperture telescope, My accomplishments included the design, development, and maintenance of both a Forth multitasking operating system and the telescope's pointing and tracking control software. This system had to be able to actively point the telescope at an object to an accuracy of .01 arc-seconds, and continuously track that object with a tracking error of less than .1 arc-second.

Tektronix Inc. Beaverton Ore. (June 1979‑ March 1980) Responsibilities included design, design analysis, and verification of custom software running on a 32-bit micro programmed processor. Special emphasis on user interface, process efficiency, communications protocol between multiple processors, and complex raster-scan graphics. Also responsible for design and analysis of self-test programs running on a 68000 based programmable instrument controller.

Floating-Point Systems. (June 1977‑ June 1979) Over three years experience design developing, and maintaining program development software for the AP120B AP190L, and FPS100 high-speed array processors. Primary responsibilities included development of a cross-assembler, simulators, and software tools used for interfacing the array processors to both large and small systems.

ADDITIONAL ACCOMPLISHMENTS

I am the webmaster for four different organizations, and am responsible for setting up and maintaining their web sites.
