劉炘武 ( John Liu )
I am an engineer who loves to build things I dream of. I am a huge believer in KISS principle because simple is the best design. I believe that codes will only work if they have been tested, and love to dive into challenging problems and come up with elegant solutions, and I like to share the knowledge with other people.
