Nov 2001-present

Online municipal bond (and other financial instrument) auction tool.
I am a consultant on the project on an as-needed basis (typically ten
hours a week, occasionally more or less).  I troubleshoot, evaluate 
design options, suggest and implement optimizations, implement requested
features, and help in testing and verification exercises.

The architecture is procedural Perl running under mod_perl talking
to a MySQL database with DBI.

Web-interfaced assessment tool.  The end product will allow instructors
to create banks of questions from which assessments can be built.
It will also allow students to take the tests, store the results in a
database, etc.  Currently there is a simple interface for creating simple
questions and storing them in a database.  There is a "latest build"
(not guaranteed to be always working) at

October 1999-April 2000

Web-interfaced database tool for managing employee contact information,
skills matrices, resumes, shared files and surveys.  (Dates are
approximate-- I was building prototypes as early as October, but more
earnest work really began in November or December.)  Demo at

August 1999-October 1999

Built a (simple) 3D vector graphics library.  Extended Lincoln Stein's 
GD.pm, then integrated that extension with a pair of modules that 
manipulated vectors and groups of vectors.

July 1999-August 1999

Started a project to create a Perl course (I was moved on to other things
before it was completed, but I gave a scaled-down version of the course
later on).

Wrote a Web-based image catalog and a (simple) interactive regular expression
practice engine.

July 1997-March 1998

Guided the re-writing and further development of MuniAuction's municipal
bond auction software.  Took them from the 2000 line demo to the 20,000
line version they (quite successfully) went live with.

July 1995-March 1998

Various projects for Shodor.  The majority of the Perl work here involved
CGI scripts, which usually talked to come computational engine written
in C running on the same Unix box.  Various and sundry other projects.
The "standard" program I wrote would interact with a user through CGI,
printing HTML forms dynamically, translating input into parameters
for the C program, piping output to it, and sending back new HTML.
They also managed archives and logged usage.  During this time I also
worked with Java versions and Macintosh versions of the same programs.
It's rather hard for me to say what fraction of my time was spent on Perl.
My hands were in it on a regular basis for nearly all of that period.
