I use GraphQL within Gatsby quite a bit at the moment so interacting with a GraphQL endpoint is something I am very comfortable doing. I have played around with Apollo both on the client and Server, and have an understanding of how to setup a schema and resolvers. At this point I know GraphQL is something I want to dive into deeper and would love an opportunity to get into some more advanced topics like data-loaders and caching strategies, or even looking into Relay Modern instead of Apollo or vanilla GraphQL on the frontend.
