Head of learning at Instil, delivered over 1,000 training events and author of over 40 training courses
Garth Gilmour gave up full time development back in 1999 to teach and mentor full time. Since then he's delivered well over a thousand courses and workshops to all kinds of programmers from all kinds of backgrounds. He started teaching C++ to C coders, then Java to C++ coders, then C# to Java coders and now teaches everything to everybody, but specializes in Kotlin.
Although self-employed for most of this career, he came to roost six years ago as head of learning at Instil. As part of that role he speaks frequently at meetups, presents at conferences, accompanied by Eamonn Boyle, and co-organizes the Belfast BASH series of developer events.
