Front-end + Back-end developer + Sign NDA

Hello, NDA required We are busy with a social media project. We need full stack (Frontend and Backend) developers who can join us. You will be hired first for a test project, to see if you fit in our team eventually we hire you per hour. You must have knowledge of: Javascript, PHP, Java and C-code. When you have experience on both Web + iOS + Android and work on an Apple. That is even better. We do not want teams, we want a developer. First project: Integration of communication tools in the design layout for web, responsive (bootstrap). This will not be a framework, this is pure HTML5 / Javascript coding. All functions are developed (and continuous in development) on the backend, and our designer delivers the designs. You must combine them with all features. The features are a combination of WhatsApp and LinkedIn (design and communication). Again for the ones who cannot read: - functions are developed (and continuous in development) on the backend - designer will deliver the designs (PSD and output) >> You must combine them. Trial will be to see if you can listen good, work good in a team, and deliver perfect work. Budget for demo: $500 - $750
