Custom Programming

Web apps, tools and back-office systems built to fit how your business actually works.

Custom Programming illustration

Sometimes a plugin or SaaS tool gets you 80% of the way and the last 20% is where your business actually lives. That's where custom programming comes in: purpose-built code that does exactly what you need, integrates with the systems you already use, and doesn't lock you into somebody else's roadmap.

Since 2000 we've built membership systems, map-based limousine routing with live pricing, IDX real-estate search for RMLS, XML content engines, document libraries and dozens of integrations between websites and third-party platforms. The code is clean, documented and yours.

Questions about custom programming

Primarily PHP 8, JavaScript/jQuery and MySQL, plus HTML/CSS, XML/JSON and API integrations with third-party platforms.

Yes. We regularly take over, debug and extend existing codebases, and we'll tell you honestly whether to refactor or rebuild.

No. When we say "apps" we mean web applications: tools that run in a web browser on any computer, tablet or phone, with nothing to download from an app store. We don't build native iPhone or Android apps.
