Hi, I would definitely be able to help you in creating an API for this project. If you're interested, some of the things we can discuss is related to the scale of the number of users that you're expecting will use your app, size of the data you're looking to store, design constraints, daily min and max number of users, hosting, etc. From there we can look into architecting the system involving the software stack we can use. Feel free to reach out to me, and we can discuss this project in more depth if you're interested in working with me.
