Android Developer Shortlisting (Paid Demo Project)

Hello Developers, I'm looking for a long-term Android developer to work on different projects with me. I would like to start with a basic and tiny App where user can share funny picture, emoji, stickers etc. to others through different messaging Apps like WhatsApp, Facebook Messenger, WeChat etc. Please note this is a paid demo project to shortlist good candidates for bigger projects. I am attaching Wireframes for you guys to give me a realistic budget for this tiny App. Design files will be provided after the signed NDA. This is a 3 screen App and should be mobile and tablet optimised for various device resolutions (portrait mode only). All the data should be stored on a server where I can keep adding new content without updating the App in the store. Flawless integration of In-App purchases is very important feature. It should be compatible with the latest version of Android and SDK (Studio). - Non-Disclosure Agreement(NDA) need to be signed. - Programmer must be able to communicate with me via English. - Serious, professional programmers only. Should be able to develop simple Apps quickly. I will have the code reviewed by a Senior Developer, so make sure the code is well structured and commented. - Should be able to implement In-App Purchases very well and have experience with it. - Should have live Apps in the Appstore. (Quantity doesn't matter, Quality does) - Some upfront will be given but the rest will be upon Google Playstore approval. Further details will be provided once the NDA is signed. Kindly send your portfolio/work for review. Looking forward on building long-term business relationship. Regards, - Z
