Help with Ionic Mobile App - Logic and database functionality

I need help with the logic functions of an Ionic 4 app I am currently building for iOS and Android. I have project managemen, UI/UX experience and have all/most the screens I need for the app (Ionic pages), but I need someone with functional skills to help build the logic for the app - login functionality, fingerprint AIO plugin setup, collect profile data locally, pulling sql data locally based on user information. Ideal candidate would have Ionic, Angular, SQL experience to help me complete what I need.
