Expression 37 specialises in the long-term support and maintenance of business-critical ExpressionEngine and Craft CMS websites. Most clients come to us with an existing site that needs a specialist to take proper ownership of it, whether that means a major version upgrade, taking over from a previous developer or agency, or ongoing retainer support. All work is handled personally by Karl. If your website matters to your business, you are in the right place.

A meaningful part of the work we do at Expression 37 involves inheriting Craft CMS sites that were built by developers or agencies who are no longer involved. The circumstances vary, but the practical challenge is always similar: a site you didn’t build, with code you didn’t write, and decisions that were never documented.
If your Craft CMS site connects to any external service, whether that’s Stripe for payments, HubSpot or Salesforce for CRM, or Mailchimp for email, you have a dependency that you probably don’t think about until it fails. Integrations break. Here’s why they fail and what to do about it.
Craft CMS has a strong but relatively specialised developer community. The difference between someone who has built seriously with Craft and someone who has touched it once or twice is meaningful. If your site runs on Craft and you need ongoing development or support, knowing what to look for matters.

It's always a nervous decision making the right choice of web provider when you have a large-scale project to be developed such as the York GPVTS website. Thankfully we made the right choice going with Karl at Expression 37. Karl has been excellent throughout the whole process of the project, working very closely with me and other members of the York GPVTS staff to ensure the site was built to our exact requirements. The end result has been truly impressive and we have had fantastic feedback from both internal staff and the specialist trainee doctors that use the site on a regular basis. Since the site has launched we have requested numerous development updates and modifications that are typically required of a project at this level. Karl has never failed to deliver these requests, often adding new ideas and suggestions to help improve the scope of our initial ideas. If you are looking for a solid, reliable, and friendly web developer, then Karl is your man!
