Dave Cross
I wrote some books (Perl Taster, Data Munging with Perl, Perl Template Toolkit). The most recent one is GitHub Actions Essentials. I blog about Perl at Perl Hacks (https://perlhacks.com/). I built Planet Perl (https://perl.theplanetarium.org/), CPAN Dashboard (https://cpandashboard.com/) and a few other bits and pieces.
London.pm was my idea. Sorry about that.
I've long been a regular speaker at European Perl and Open Source conferences, but this is my first time at a North American conference since OSCON was in San Diego about twenty years ago.
