Hi sir, I read your project description, and I am glad to tell you that i have a past experience on working on Wi-Fi API for android and server-client communication over Wi-Fi, I have worked through a Hotspot application, with some extra features, you can check my portfolio for some screen shots of this app, but it's a light UI prototype, so I have the required experience to have this project done in short time, with the desired performance.I will be glad to hear from you.
