Inviqa will sponsor drink for this meetup.
Dan Blows is the Head of Solution Architecture at Hyperion X. He's been working with PHP since v4, and started using Symfony v1.2 in 2008. He's already upgraded three large codebases from PHP 5 to PHP 7, including one from v5.3. After building a pension calculator he realised that he needs to give talks at conferences if he's going to eat after he retires.
