Who you'll work with
Crazy Logical is a specialist integration business, led by the engineer who does the work.

Hi, I'm Kewan.
I founded Crazy Logical to do one kind of work well: the integration work that sits outside an agency's usual web development.
I've spent more than 20 years building software and integrations, working with many different APIs, from modern REST and GraphQL services to legacy SOAP endpoints.
I'm happy to work directly with your developers, either planning an integration they'll build or building the integration layer while they build the site. I don't build websites, so there's no overlap with your team's work.
I work behind your agency, white-label, so you keep the client relationship. Every engagement starts with a defined scope and a fixed price, agreed before any build work begins.
I'm based on the Gold Coast and work with agencies Australia-wide.
