Software solutions

Lokeren, Belgium


With more than 20 years of experience in analysis, design and development of software solutions, I know how important it is to feel and see the software solution, before starting developing it.

With a wireframe and/or prototype we can correct misunderstood functional requirements and processes, and work on the look and feel until satisfying, before it’s too late in the software development process.
