Hi there,
I have been working in Android development for 2 years now. I have only really worked in the context of the FTC SDK (the space my robotics team works in) however I am a very fast learner, I can most likely get you the product in a timely manner, i am a student so I do not have other jobs just freelancing things I pick up. Hope to work with you soon in the future, if you want to discuss further we can just let me know, thanks.
