Arbitrage trading bot

I am looking for a programmer experienced with exchanges like [login to view URL] and bitmex.com. What I need from the programmer is to build auto trading robot which will do: 1. Compare prices between BITTREX / KUCOIN / BitMEX / and more.(Specification that you can add exchanges to compare.) 2. When the price difference reaches the specified amount, sell order at A and buy order at B. 3. And sell (exit) the order when gap filled or minimal % profit (set in setings) filled. 5. I want easy to use interface either web / html5 / java or Python to work with the bot.
