I build applications a second developer understands right away.

Who's
building

I'm Maarten — an Application Expert from Donk, Belgium. By day I design, build and maintain applications; the common thread never changes: clean layering, decisions you can explain, and code a second developer understands right away.

Away from the keyboard I chase the same discipline in triathlon: train, measure, adjust. Not by accident, one of my open source projects is a triathlon calendar.
