Hi everyone, I need a backend for a future mobile app. About the app (not part of this project): The app tells you when to cut/prune your plants and flowers. A user registers, tells in the app which plants he has. The backend keeps track of this, and sends out push notifications to the device when it's time to cut/prune the plants. This project is for the backend (CRUD, authentication, API) of this app. The backend should be a place where an admin can add plants, genera (plural of genus, genus = family of plants) and pruning periods. The backend also keeps track of users, and devices. CRUD * The system has a CRUD backend for the whole model, including simple clientside search in the data tables * For the description of plants and genuses, html should be used (tinyMCE or similar) API * The system should support a serverside search function that searches in the plant and genus name, latin name, and descriptions. * The system has api methods for - List of all plants - List of all genera - List of plants for genus x - List of plants for user x - List of genera for user x - List of pruning periods for plant/genus x Etcetera. The full list is in the attachment (sheet API_methods). Authentication * Only as an administrator user, I can see the registered users * The system should be able to authenticate a backend user through email and password * The system should be able to authenticate an app user through the combination of email address and a 4 digit pin code * A reset password / forgot password function should exist for backend (HTML) and app (API) users. * The system should encrypt the pin code, which is only used once until a user re-installs * The system should support multiple device(token)s for a single app user as authentication Other * The system should be able to send push notifications for Apple (http/2 !!) and Google periodically * Example: every 24hrs the system checks which plants are ready for pruning, and sends a notification to each user that has this plant. Max 1 notification per user per day: e.g. "Your Plant A, B and C are ready for pruning. Do this before [end of pruning period]" * The system should be able to handle push notification errors, such as when the app is uninstalled * The database and API is ready for future multilanguage. Default = Dutch * The system should have a possibility to send a free-text push notification to a user In the attachment you can find a basic domain model. * This might change a bit, but probably not much. * What's missing in the model is an authentication token. I don't know at which level that should be saved. That's basically it. I am open to different types of frameworkes and techniques. Please tell me what language, platform, frameworks and techniques you plan to use. The project will have milestones for 1 a fully functional CRUD backend, 2 a fully functional API 3 Scheduled (recurring) push notifications functionality 4 full functionality of all above with the app. Building the app starts when API is ready. Abovementioned are the requirements as I see now. Some extra things may appear during the project.

Hi, Just to clarify some points : 1) In which technology you want backend? 2) How you want to notify users about their plant? I mean by dynamic way or manually by pre-define time [from backend]?

Only Backend [including API, Push notification] : € 520 Full Functional App [From given PSD design] : € 870 Regards, Jigar
