David Manners - originally from the UK - now works as Senior Software Architect at Magento solution partner Sitewards in Frankfurt, Germany.
David was a Magento Master in 2016 in the “mentor” category and he has been working with Magento for over 5 years. Besides his job he has been entertaining his 2 kids and hosted the video series MageEngage where he interviewed many community members about what they do besides Magento.On August 29th he announced on Twitter (twitter.com/mannersd/status/902573999070121984 ) that he will be joining Magento’s Community Engineering Team in October. Sander and I were eager to ask David why he is making this move and what we can expect of him in his new role.

I've created a version of this chart/pyramid applied to CRO which you can see below. It contains the options we have as optimizers and tools and methods we often use to gather data.
