Daniel Leech, Techincal Team Lead


16 years experience in software development with a focus on PHP applications and libraries. My time has been split between writing open source projects and involvement and leadership of projects in the areas of e-commerce and content management.

I am member of the PHP and Symfony community and I give talks at work, meetups and conferences.
