Work Experience

Follett School Solutions, McHenry, IL (2012-now)
Book Wholesalers Inc, McHenry, IL (2007-2012)

BWI was a wholesaler of library books to public libraries. I drove sorely needed upgrades to BWI's TitleTales website since the company's 2007 move to McHenry. After BWI was sold, I transferred to Follett School Solutions.

Senior Programmer

  • Inherited and modernized e-commerce web app of 100,000 lines of PHP under Apache.
  • Created a modern development environment for the app. My predecessor had one codebase: the production server.
  • Implemented version control, automated testing, bug tracking, coding standards, continuous integration and a stable release process.
  • Design, coding and testing of ongoing improvements to the app. New development was done with modern Perl techniques.
  • Planned and implemented a 15,000,000-document search engine in Solr & Lucene to replace an existing search application using Oracle Text.
  • Created and evangelized the company wiki in MediaWiki. It grew to 3,000 pages in its first year and is now an integral part of company workflow and culture.
  • Received the "Follett Values In Action" award, a $500 quarterly prize, for the company wiki.
  • Created Cacti monitoring system to track server performance trends.

Socialtext, Palo Alto, CA (2006-2007)

Member of Technical Staff

  • Drove release of Socialtext Open, the open source wiki offering.
  • Public face of Socialtext to the open source user community.
  • Documentation and infrastructure improvements to improve release infrastructure and installabilty of Socialtext Open.
  • Code quality improvements and automated checking via Perl::Critic.

Follett Library Resources, McHenry, IL (2001-2006)

Follett Library Resources is the leading wholesaler of K-12 library books in the U.S. The Titlewave online application helps librarians select materials for purchase.

Web Applications Manager (2002-2006)

After being promoted to manager, I scaled the department upward to include six programmers and a system administrator.

  • Grew and led team of six programmers and system administrator
  • Started migration of PHP codebase to object-oriented mod_perl.
  • Defined software construction processes used by all programmers
  • Interviewed and hired all programmers
  • Directed long-term system administration goals
  • Chief architect of web systems infrastructure
  • Gave training classes for staff and sister companies
  • Planned future growth with my counterpart on the project management side of the house

Project Leader / Sr. Software Engineer (2001-2002)

When I started, there was one programmer, one system administrator and no repeatable process. Releases were made by FTPing tarballs to production servers, and version control was made by occasionally zipping up the source.

  • Project manager and lead programmer for all projects
  • Lead programmer/architect for the Titlewave team
  • Implemented CVS & Subversion version control systems
  • Created new infrastructure for the site using PHP's object features
  • Implemented software process and coding standards

Follett Software Company, McHenry, IL (1991-2000)

FSC is the leading creator of library automation software for the K-12 market. If you checked out a book in a school library in the past 25 years, chances are it was done with a Follett Software circulation system.

Sr. Internet Engineer (1996-2000)

  • Created the company-wide intranet and external website infrastructure
  • Created all intranet applications for all departments

Software Engineer (1991-1996)

  • Designed, coded and tested library automation software in C and C++.

  • Wrote Pascal software for retail stores: Point-of-sale system; purchase orders; inventory; email
  • Wrote back-office systems in BASIC, COBOL and SPEED II 4GL: Accounting; inventory; email

Open Source

Some of the projects I've created and contribute to include:

ack
I created the widely-used text search tool ack (sometimes packaged as "ack-grep") in 2006. As ack has matured, my role has changed from creator and author to shepherd of incoming patches.
The ack website, beyondgrep.com, also is a hub of information about other code search tools to help users decide which tool best fits their needs. The site gets about 8,000 unique visitors each month.
bobby-tables.com
This site is a collection of information to help novice programmers understand how to properly use parametrized SQL queries to prevent SQL injection attacks. While I created the site in 2008, it is now based on community content. Source for the site is kept on GitHub, with contributions coming in just like patches to a code-based project. Around 4,000 unique visitors use bobby-tables.com in a month.
WWW::Mechanize
WWW::Mechanize is a Perl module that allows easy navigation of websites, acting as a web browser in an object. Created as a fork of WWW::Automate in 2002, I maintained Mech until 2012. It is now slated to become part of the standard libwww-perl library. Its sister module, Test::WWW::Mechanize merges the convenience of Mech with Perl's automated testing ecosystem.
Perl 5
As a member of the Perl 5 Porters, or core Perl developers, I contributed patches to the C source code to make it more maintainable and with safer constructs. I performed regular static analysis on the C code and strengthened the compiler warnings to check for questionable code.
Perl::Critic::Bangs
A collection of policies for the Perl::Critic static analysis framework.
Test::Harness and prove
During the time I maintained the core Perl module Test::Harness, I created the prove tool to encourage test-driven development by making test execution simpler from the command line. prove is now shipped with every Perl distribution.
Perlbuzz
Perlbuzz is a news site about Perl 5, Perl 6 and Parrot. As more Perl blogs have become popular, Perlbuzz has mostly become a stream of stories, selected by me, fed primarily through the @perlbuzz Twitter feed. Perlbuzz reaches almost 7,000 readers and followers each week.
Parrot
Parrot is a virtual machine, written in C, for running modern dynamic languages like Perl 6. In the late 2000s, I worked to increase stability of the code by increasing the number of compiler warnings checked, running static analysis tools like splint, and instrumenting the code.
White Camel award, 2005
Awarded one of three White Camels, an annual award for service to the Perl community.
