Hello. I am very experienced Android developer, more than 6 years as android developer(4 years as freelancer) and more then 15 years as programmer. I have dozens happy clients with completed projects. And I am free now, we can begin today. I can resolve any problem in you sources or create totally new application in any complexity. I have not reputation here because usually I work in another place(upwork). I can give you my profile link in chat, if you interesting.
I work only by hourly rate $25 for you.
