Sherine Elbanhawy

Founder, Rowayat

I was introduced to Guillaume to create a new website in WordPress linked to a separate website for a shopping cart. I wanted to use a particular cart I was familiar with and had confidence in. Not only did Guillaume do a really sharp job on the new WP site – his area of expertise, but he made it a seamless transition to the shopping cart and back to the website. It flows beautifully and he told me he’d never used that cart software before. I was impressed by the quality of his work – artistically, and his coding skills. Price was very competitive and it is great to see the professionalism in his workmanship.
