Case Studies

How Expression 37 has helped businesses with business-critical ExpressionEngine and Craft CMS websites. From sites running on outdated versions with no developer support, to integrations that had grown beyond their original agency, these are the situations we work with and how they turned out.

Capula Craft CMS
Technology & Digital Services Full Build & Retained Partnership

Capula

A complex corporate website built from the ground up on Craft CMS, with a deep content architecture spanning case studies, sector pages, solution offerings, and a live vacancy board. We have been the technical partner since 2021, maintaining the platform, resolving compliance issues, and building new capability as the business has grown.

City Permits
Parking & Traffic Management Emergency Rescue

City Permits

A live, payment-critical platform that could not process a single transaction and was failing PCI compliance scans. We rebuilt the application on modern PHP, fixed three separate payment gateway bugs that had silenced every payment attempt, and migrated to Stripe, returning the business to full operational capability.

Client feedback:

Upon completion of the Thornfields Primary Care Trust website, we had no hesitation on asking Expression 37 to help out with some further development updates with our main company website. As with the Thornfields project Karl and his team turned around our requests with flawless speed and efficiency, often adding further advice and guidance on how to best implement the features required. If you are looking for a tried and trusted ExpressionEngine specialist we strongly recommend these guys.
