Have document to detail the app the processes and flow. Looking for a reliable person, with experience, to build the app and service it as needed. Some design aspects need to be determined but the app processes are in pretty well defined at this point. I will send you the app document after we have a discussion about your skills. The app is a directory of information related to specific topics. App users will navigate the app using data selections (city state, category) and then results will be displayed. App includes verification processes to setup an account, via email with a link to click, and processes to make purchases in the app, record those purchases in user profile. The purchases will be made using stripe.com. When hired you will build he app structure, using appropriate data techniques to satisfy app processes, and design the screens for navigation. Changes may take place during building of the app so you must be flexible and use your experience to determine the best course of action.
