Hello everyone,
I want to ask if anyone is interested in having me build a best-practice GraphQL API on top of your existing REST or gRPC APIs, completely free of charge.
We're currently running a pilot with our open-source GraphQL runtime, which you can check out at https://tailcall.run/, and would like to test it out with some real production APIs. Anyone who is interested, please comment and if need be we will build the whole GraphQL layer for you for free.
