Top Frappe Developers List

Please share me a list of top Frappe developers. Project is to build a Customer Information System (CIS) for a Utility Provider like Internet, Water and Electricity. Can handle up to 2 Million customer information data.

How you define top developers?

2 Million customer information alone is not big deal.

Members of this community I understand are direct users, service providers and developers. Top developers in my mind are teams or companies that are willing to create a dedicated functionalities in a separate custom App.
