UX/UI Design for mobile app

We are looking for a creative UX/UI designer to help design a mobile app for our facial recognition registration system. The application prototype has already been built in C# for desktop use and provides core functionality, with a basic UI. The app is currently very simple, there are 4 forms at present and 1 menu with 3 options, all single windows. This will be extended to include some additional enhancements we wish to make. We now need to hand over to a UX/UI expert to make the app come to life. The application will be redeveloped in Xamarin for mobile, tablet and PC. The successful designer should have solid experience with designing Mobile Apps and will suggest suitable designs and improvements to the user flows. The designs and user flows should be provided in a detailed word document with diagrams and wireframes. These will need to be reviewed by our developer and presented to our business stakeholders. We will provide you a copy of the working prototype, the company logo, the prototype technical design document, a functional specification document for the new application enhancements and some basic wireframes. We would expect suggestions of colour/fonts/layouts, detailed designs of each form/screen, user flow diagrams and wireframes. • The candidate must have good written and verbal English language skills. • We will need to see 3-5 similar design projects from your portfolio, with a description of relevance. • The candidate will be required to sign a NDA (Non Disclosure Agreement). • Only custom written responses will be considered. Bot and generic responses will be ignored. • Full service (UX/UI plus development) will be considered, however this is a UX/UI design project and priority will be given to designers with proven experience. ** IMPORTANT: When you reply, start by typing the code words: Bug Testing. This way I know you have read the complete description, instead of providing a generic response as many people do ** Thanks, Dale
