Jan 2013 - Feb 2014


When I am not working on new and innovative ways to advance blockchain based technology, I like to work outside in my garden or practice the art of woodworking.

If the weather decides it best to stay inside, I like to relax in comfortable clothes with a funny or scary movie and loved ones while we create new exciting foods for our consumption.

I don't get to play as much anymore but I do enjoy a good game of baseball, football, basketball, or pretty much almost any sport.
