About

I am Viktor Klang, a distinguished software professional mostly specializing in Developer Experience, API Design, Software Architecture, and Concurrent & Distributed programming models.

In my professional career, spanning more than two decades, I have always gravitated towards enabling others to be more productive, and as a result of this I have contributed to the standard libraries of several major programming languages, been involved in many Open Source projects, and enabled some of the largest companies in the world to bring novel solutions to market.
