Edit Android App

Hi, I am seeking an experienced app developer to polish-off an Android app on my behalf. It's basically a game with an AI character, very simple, but I would like to hire somebody to add objects to the game screen for the AI to navigate around. I would also like the selected freelancer to implement a specific algorithm, in place of my current algorithm. It is very important that the code is 100% unique and not copied or released anywhere either before or after this project is completed, by accepting this project you agree not to disclose any of the details with any third parties under any and all circumstances. I hope this quick project is of interest to you and I look forward to receiving a proposal.
