Featured work

• The Little Knitting Company

  We migrated the store to Shopify and rebuilt the catalogue structure from scratch, so customers can browse by yarn weight, fibre type, or project type - whether they're after a skein of sock yarn or enough DK to knit a sweater. The new site reflects the quality and values of the brand: thoughtful, eco-conscious, and built for makers.

• The Fibre Co.

  Woocommerce migration to Shopify, building custom taxonomy, Kit system (bundles) and A B2B self-service portal gives trade buyers independence and control. Multi-market functionality handles the complexity of selling across different regions.

• Hilton Herbs migration to Shopify Plus

  We partnered with Hilton Herbs, a global leader in herbal health supplements for animals, to migrate them from a custom CMS to Shopify Plus. Our work involved transforming their online presence into a multi-language, fully internationalised site for the US, EU, and UK markets. Integration of three fulfilment centres, improved inventory management and development of both B2B and B2C functionality.

• All For Love LondonTheme customizationMay 8, 2014

  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.
