I am doing blockchain work full-time. I have a lot of experience with master node coins and Bitcoin derived blockchains. Blockchain development is the thing I'm most interested in right now. I am looking forward to creating really useful blockchain product for the benefit of the world.
I have a lot of experience in old style Windows API programming. And I created several shareware using Windows-only technology such as Delphi more than 10 years ago. Now I focus on cross platform technology such as Qt.
