Zhengnami 

I deliver only exceptionally robust and well-designed work as a rule. Furthermore, you should know that as a principle I do not finish my work until I believe it is of the most professional quality I am able to create. My skills encompass Native iOS , Android, and Black Berry mobile development, Python or Ruby web programming, and, in addition, Xamarin iOS / Android development. I possess deep technological expertise regarding Optical Character Recognition, Augmented , OpenCV, XMPP, and OpenTok. You will find me easy to communicate with to an extent by which you may be surprised, but that is because I believe only a dedicated connection with my employer can lead to truly extraordinary creations.
