Craft CMS Developer & Support in Stevenage

Long-term Craft CMS support, version upgrades, and specialist development for businesses that cannot afford for their website to fail.

Karl @ Expression 37 ~ Craft CMS Developer, Stevenage

Craft CMS enquiries from Stevenage generally mean the install's in one of two states: ticking along unpatched, or genuinely causing problems with the developer who built it unreachable.

Karl handles every one of these himself. He's worked in Craft CMS and ExpressionEngine only, since Expression 37 started in 2007. No account manager, no wider team.

Before anything's quoted, the install gets a proper look. That's usually a fix, a version upgrade, or an ongoing retainer.

Where we typically come in:

  • Aerospace and technical manufacturing firms needing Craft sites that stay accurate for a genuinely specialist audience.
  • Pharmaceutical and life sciences companies where published content carries real compliance implications.
  • Specialist recruitment sites that need application handling to work reliably, not just look presentable.
  • Businesses running complex B2B pipelines through Salesforce, needing a developer equally comfortable in Craft and the integration.
  • Teams who've been let down by agencies treating technical content like generic marketing copy.

How a typical engagement starts:

Something concrete usually prompts it: a recruitment form quietly failing for a specialist role, a compliance-adjacent page found to be out of date, or a routine security check flagging an ageing Craft install. Karl gives the codebase a proper, careful review rather than a surface-level glance, and businesses in this sector tend to prefer that scrutiny continue on an ongoing basis rather than stopping after one fix.

Common questions Stevenage clients ask:

Given how specialised our content is, do we need someone local?

No, specialism doesn't require proximity, it requires care, and that's applied the same way remotely as it would be in person. Reviews, deployments, and fixes all happen without needing anyone on site.

How seriously do you take content that has compliance implications?

Very. Anything touching regulated or technical content goes through staged testing and proper review before it reaches the live site, it's not handled the same way as a standard page edit.

Our recruitment needs are unusually specific, does that complicate the site?

It adds requirements a generic careers plugin won't meet cleanly, application logic that actually matches how a specialist role gets filled, which is worth building properly rather than forcing into an off-the-shelf form.

What's actually at risk if our Craft version is a long way behind?

Beyond the general security exposure, plugin compatibility becomes the real headache, and for a site with this much custom structure, an overdue upgrade tends to be more involved than businesses expect.

We rely on a Salesforce pipeline for enterprise sales, is that in scope?

Yes, and it usually needs as much attention as the CMS itself, since that connection is what actually turns site enquiries into tracked opportunities.

How would you price ongoing work with us?

A retainer that reflects the actual complexity involved, agreed once the scope's understood, not a flat rate applied regardless of what the site demands.

What's the best way to open the conversation?

Tell us what the site needs to do, technically and for compliance, and what's prompted you to look into this. That's enough to give a properly informed answer.

Ready to get started?

If your website is business-critical and needs a specialist who will take proper long-term ownership of it, get in touch. Karl will respond personally and give you an honest view of how we can help.

Can we help?

Most clients come to us when their site has started to feel like a risk rather than an asset. Whether the agency relationship has ended, an upgrade has been delayed, or the site has simply grown beyond what it can handle, a conversation costs nothing.

About Karl

Karl Bowers ~ ExpressionEngine & Craft CMS Specialist

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.

Client feedback:

When an serious issue occurred with our website, meaning that we were unable to upload images or documents, we soon realised that we needed an Expression Engine expert to take a look. Working in tandem with our in-house team, Karl identified the issue and quickly put a fix in place so we could get back to normal. I’d recommend him to anyone who needs assistance with an Expression Engine based website.
