Developer, developer, developer!
Most recently I have been learning about (still a lot to learn): networking, bitcoin, security, cryptography, and trading in general I wrote a command line toolkit for stock traders, more info at: https://honzajde.github.io/
My current secret project: currently it's some data gathering of real-time trading data from a variety of cryptocurrency exchanges (written in Go). I wish I had time to extend this into a toolset that would make trading cryptocurrencies much easier.
My best finished project: http://www.anywheresms.com - user friendly SMS gate without ads with low prices.
Best spent time: with my family
My mission: Never stop learning.
