Stripe payment Backend implementation in . net core api

Need a experienced .net core api developer with Stripe . The client is Android/IOS which will open the stripe widget to collect Card, bank account and backend will be in .Net core Api to create customer object, empheral keys and so on. SQL would be good to have but not necessary to save the data into sql. Deadline is really tight : 2-3 days , need to work with mobile dev during IST time to complete this. Note I am not looking for any MVC/Web sample. it must work with the mobile.
