Expression 37 specialises in the long-term support and maintenance of ExpressionEngine and Craft CMS websites that businesses depend on every day. Most clients come to us when their site has become difficult to trust, whether the developer relationship has ended, a major upgrade has been delayed for years, or the site has simply grown beyond what the original build can handle. All work is handled personally by Karl. If your website matters to your business, you are in the right place.
Get in touch and Karl will respond personally with an honest view of how we can help.

Expression 37 works with a small number of clients at any one time. These are some of them.
Every client came with a real problem and a website they could not afford to have fail. Here are a selection of the engagements and what was involved in each.
Craft CMS
Custom PHP
ExpressionEngine
Practical writing on ExpressionEngine, Craft CMS, and the kind of problems that build quietly until they can no longer be ignored. Written for business owners, not developers.
Slow responses from a web agency usually come down to capacity, not your website. Here's what causes the delay, what it costs a business-critical site, and how to tell if you're already exposed.
I started working with ExpressionEngine in 2007. At the time it was one of the most capable platforms available for complex content requirements, and the projects I was being handed reflected that: membership sites, booking systems, trade portals, internal tools built on top of a CMS.
ExpressionEngine and Craft CMS are not generic frameworks. A developer without platform experience can fix some things and quietly create others. Here is what platform specialism actually means when your site handles real business operations.
Karl founded Expression 37 in 2007 and has worked exclusively with ExpressionEngine and Craft CMS ever since. He does not take on work in other platforms and does not hand work to other developers. Expression 37 is deliberately small, because the kind of support that matters to clients with business-critical sites is specific to their site, not something that scales in the conventional sense. If you work with Expression 37, you work with Karl.
