Databases with connectivity to APIs of all major wearable devices

I'm looking for an experienced programmer to develop customizable databases for me that have connectivity to APIs of all major wearable devices. I need a database that can easily store and work with large amounts of data, so I have decided to go with SQL databases. Furthermore, I need the database to be integrated with the APIs of all major wearable devices, so an API integration is necessary for this project.

The database will be used for healthdata, to be accessed by website and apps.
