Simon is highly skilled at the technical aspects of shopify site creation and has an intuitive understanding of what is required artistically, as a designer. In the last project he undertook for me our online shop sales increased by 40% as a direct result of his work. Highly recommended.

Simon was a pleasure to work with from the start. He was recommended to me by a mutual friend and fellow web developer so I already had great confidence in his work. He was patient, kind, always helpful and super efficient. I could not be happier with my website and I am very grateful for all of his hard work. I shall definitely always be using Simon to help with any future developments I want to make to the site. I would recommend him to anyone, including the Queen.

I asked Simon if he could make a change to his own theme design for me, and he responded right away that he could, and completed the job that very afternoon! Highly recommended!

Simon explained his process for timing, payment and service professionally and did exactly what we requested. Changes were made sooner than I expected which is always nice. We will work with him again in the future
