Hi There,
I have read your post and also checked the attached screenshot. As per that I come to know that you would like to get build an android application for office file management with mentioned features.
Likewise here, Freelancer also allows us for a quality approach to client, we have a limited area to describe all. so I want you to invite me for Personal Message Chat here in the same Platform to discuss more and tell something beyond this info which you might be looking for and that discussion will surely conclude us with a proper estimation.
We Believe In order to achieve your goal or Scope, We have a bunch of skillset like Native(Android & iOS), PHP(Including all Major Frameworks), Dotnet, Node JS, Angular JS, React JS, DB(MySQL, Realm, FirebaseDB, MongoDB, Oracle), Different third-party SDKs and APIs.
We are a team of highly experienced(>2 Years) People which covering the area of Designing, Development, Backend & APIs, and QA.
