20+ Years of writing ColdFusion, and we've seen things
ColdFusion has been the backbone of serious web applications since the mid-nineties. We've been writing it since 2000 - through every version, every acquisition, and every developer who swore it was dead.
ColdFusion does a specific set of things exceptionally well - rapid application development, database integration, complex business logic, and server-side processing that's fast and readable. We use it where it's the right tool, and we've been using it long enough to know exactly when that is.
Starting from scratch with ColdFusion as the backend of choice - whether that's because your team knows it, your infrastructure runs it, or you simply want a developer who won't try to talk you out of it. We design and build production-ready CF applications that are clean, maintainable, and built to last.
You have a ColdFusion application that works. It just needs someone who can get into it, understand it, and keep it moving - without breaking what's already there. We've worked in other people's codebases for over two decades. We know how to read code we didn't write.
Moving from an older CF version to a current release, or modernising the front end of a CF-backed system without touching the logic underneath. We know what breaks between versions, what needs rewriting, and what can stay exactly as it is.
Before anything changes, we understand what's there. Every system has its own logic, its own quirks, and its own reasons for being built the way it was. We map it before we modify it - so nothing breaks that shouldn't, and nothing gets rewritten that doesn't need to be.
The instinct to modernise everything at once is expensive and risky. We identify what's actually causing the problem, fix that, and leave the rest alone. Targeted intervention over wholesale rewrites - unless a rewrite is genuinely the right answer, in which case we'll tell you why.
Legacy systems often have no documentation. After we've worked in yours, they will. Every change is recorded, every decision explained. The next developer - including us, twelve months from now - will know exactly what they're looking at.
Front end, back end, database, server - handled by the same person who read the brief. No handoff between someone who knows CF and someone who knows CSS. No blame gap when something at the seam doesn't work. Just a clean line from problem to solution.
If you've ever had to justify your technology stack to a developer who spent the first week Googling basic CFML syntax, you'll understand why this matters. We don't need onboarding. We arrive knowing the language, the quirks, and the gotchas - and we get to work.
Production systems don't break during business hours. We understand the stakes of a live application going down, and we treat your system with the same urgency we'd want applied to ours.
ColdFusion runs on Adobe ColdFusion and the open-source Lucee engine. We're comfortable with both - and with the hosting environments, server configurations, and deployment pipelines that keep them running reliably. We don't just write the code and hand it over. We make sure it actually works in production, under real conditions, with real traffic.
Version compatibility, session management, scheduled tasks, mail servers, datasource configuration, PDF generation, web services - the parts of a CF application that sit outside the code editor but inside the application's reliability. We've dealt with all of it, across multiple platforms and hosting environments, for over two decades.

Not only did Paul deliver a great site at the front end, but he can also organise the back end that provides the lead information etc. Great communication and quick work even when I kept asking for changes.
