I'm the creator and maintainer of ack, the greplike code search tool.

I maintain bobby-tables.com, the guide to preventing SQL injection.

I maintain altbox.dev, a collection of open source alternatives to standard *nix tools.

I've been in open source since the 1990s, mostly in Perl. Some of the things I've written:

• WWW::Mechanize, the handy web browser in an object.
• Test::WWW::Mechanize, the WWW::Mechanize extension to make automated website testing easier.
• Module::Starter, the first tool to create a skeleton Perl module distribution.
• prove, the standard tool for running Perl tests

Other projects I'm involved with:

• Perl::Critic, the Perl static analysis tool. I'm currently a maintainer.
• Perl::Critic::Bangs, my custom set of add-on policies for Perl::Critic
