Barend Garvelink

Barend Garvelink is a skilled Java, Scala and Python programmer, but promiscuous to the point of writing C# code. He started dabbling with QBasic at age twelve and hasn’t stopped programming since. 

He taught himself object-oriented and functional programming along the way, studying it in college and eventually turning the hobby into a profession.  

Barend has a broad expertise and has worked successfully on everything from mobile apps to enterprise servers and the cloud. Barend enjoys chipping away at complex programming problems, prodding at them from all sides until an elegant solution clicks into place. He is meticulous about writing clean, clear and well-documented software. 

He is a trainer, because he enjoys sharing knowledge and helping others improve their software craftsmanship. Like he did at ING as the lead developer on the mobile banking app for Android and as a data engineer at Quby.
