    We have a Go Chess board (“Board”) which you can also consider as an electronic toy. We embedded a mini computer with Android system within this Board. It functions like a cell phone in a Board, however this “cell phone” doesn’t have a screen and we aren’t planning to put one in. Currently the Board has to connect/go through a server in order to connect to a smart TV to perform screen mirroring/projecting. Our goal is for the Board to be able to directly connect to a Smart TV as long as they are in the same wifi network. So that an intermediary server or an HDMI cable is not needed between the Board and a smart TV to connect using Wifi. We are looking for a developer to develop an app on Android system that will run simultaneously with the Board s...

Technically, any software program as long as I can EXPORT the data in a CSV format type file for bulk upload to new hosting website. Does this make sense? CSV format is based on integration features to a future website host like Big Commerce, Shopify or even OC, I am flexible. FYI, I am a previous paying client on FreeLancer years back.
