Services
Expression 37 has worked exclusively with ExpressionEngine and Craft CMS since 2007. That single-platform focus means close to two decades of concentrated expertise, not a general web development practice with EE and Craft as two items on a longer list. When something goes wrong, needs upgrading, or needs building properly, that depth of experience makes a tangible difference.
The work is focused on businesses whose websites matter to how they operate, sites that handle transactions, manage members, deliver services, or underpin day-to-day commercial activity. Expression 37 works with a small number of clients on an ongoing basis, with all work handled personally by Karl. There are no account managers, no handoffs to junior developers, and no one else involved.
If you are not sure yet what you need, a conversation is a sensible first step. Karl is happy to talk through your situation, give an honest assessment of what is involved, and tell you whether Expression 37 is the right fit.
