 Programming Experience

This page is rather out of date!

I started programming in 1983 while a sophomore in high school using the BASIC language on a Commodore 64 computer.  Since that time I have taken several computer science programming courses and applied this knowledge on various projects for engineering classes and while working at Project Vote Smart and as a contract programmer.

Java Programming in Java since November of 1997 - although paid to do it since January of 1999. Lots of experience with the Swing, Reflection, and Collections API's. Some experience with JDBC, Tomcat, multi-threading, and XML-RPC for Java.
Python Started using Python/JPython in October of 1999 at contract job at Jenkon International. What a cool language!
C++ Started learning in July of 1997 by reading books and writing small programs using MFC with MS Visual C++ 5.0.  No large programs written yet.
C Took two programming courses using C staring in 1990.  Used C in several projects for engineering classes while an undergraduate and a graduate student.
Visual Basic Started learning in May 1997 so as to supervise programmers using it for database applications.  Started writing small programs in July of 1997 using Visual Basic 5.0.  No large programs written yet.
Perl Used extensively for several years starting in the Fall of 1994 for tasks at Project Vote Smart.  Wrote scripts to convert comma-delimited files extracted from a custom database into a hierarchy of web pages.  Also used for writing CGI scripts to perform data look-up by ZIP CODE and the posting of messages on web site.  Taught Introduction to Perl class at PEAK.
HTML Wrote web pages with vi for two years.  Latest version I learned is 2.0 using tables and frames.
SQL Read up on this language from a couple books on databases and used it with a Perl module for presenting data in HTML.  Use it on occasion for querying data from MS Access 97.
Assembly Gave an introduction to and demonstration of the use of the AMD 29000K uP instruction set while a graduate TA.  Used some x86 instructions for assignments in engineering classes.  Worked with simplified instructions sets in computer architecture classes.
Pascal Took a course in Pascal in 1988 and used it for class assignments into 1990.
FORTRAN Took two courses in this language 1987-1988 and haven't used it since.


Apache Configured, installed, and managed Apache web server versions 1.0-1.1 for two years at Project Vote Smart.  Utilized FastCGI module to speed up certain CGI programs.
MS Access 97 Using currently to create sample databases for Visual Basic projects.
MATLAB Used this math simulation package for several years in projects for engineering classes.  Last used in 1993.
IC Station
Used 7.X-8.X versions of this integrated circuit design package to layout 4 integrated circuits between 1991 and 1994.  Wrote rules files for device layout, verification, and extraction for two different GaAs fabrication processes.
SWITCAP Used this switched-capacitor circuit simulator for class project in 1993.

Operating Systems

NT 4.0
Installed server and workstation editions at work and at home.  Currently use NT Workstation for most tasks.
Linux Installed Linux 1.2-2.0 on servers and managed network services for two years.  Services included: Apache web server, gopher, BIND, sendmail, routed, dial-up modem connection, and proxy firewall.
Sun Solaris 
2.5 for Intel
Installed OS on webserver machine and setup perl, apache, gnu c, and various utilities.
Windows 95 Installed and managed network of Windows 95 clients for one year.
Windows 3.11 Installed and managed network of Windows 3.11 clients for one year.
MacOS Used Macintosh computers for Pascal programming, desktop publishing, and graphics for several years.  Last version used was 7.X.

Current Projects

I will post these programs on my web page as freeware when they are ready.

1. Educational program simulating the motion of planets and other masses under the influence of gravity (Java and VRML).

2. Diet balancer utility to evaluate a person's meeting of their nutritional needs utilizing USDA Food/Nutrition data (Java and ObjectStore PSE object database).
