Emma is owner, director, front-end and back-end developer (and everything else in-between) at her company The Web Bakery. She has been building websites since 1999 when she did a website for her husband's business and wanted to get back to her design roots. This was back in the dark ages of Frontpage, and yes, she will admit to using it at the start, followed along closely by Dreamweaver until she taught herself to code properly with HTML then CSS, PHP and Javascripts.

She started her own website business in 2002 and added 2 more businesses (related to dog agility - her hobby at the time) over the years but has now closed those down to focus solely on her passion of creating websites; though now she only codes and gets others to do the design work as she has realised that's what she really loves to do.

Oh, and by the way, she is a Shropgeek :)
