Hi! I'm relatively new to freelancer.com but I go way back with programming. I'm an expert at Android programming and I specialize in making apps which function as services and don't have GUIs. I've already done something similar to do this before so I'm pretty sure I can do this for you. Have a look at my profile to see what previous clients had to say about me or drop me a private message to talk more. I've, so far, mantained a perfect record on this website with 100% project completion rate and client satisfaction. Hope to hear from you soon. Have a good day!
