Go & GraphQL Backend Enhancement

I need a seasoned Go and GraphQL expert to revamp my backend. Currently, my responsive structure is as follows: - category { id, name, items } I want to introduce a subcategory within the category structure, resulting in: - category { id, name, subcategory { id, name, items }, items } Key Details: - Retain existing category fields: The id and name fields in the category should be preserved. - Utilize existing subcategory schema: I have a pre-defined schema for the subcategory, so there's no need to create one from scratch. - Modify subcategory schema: The subcategory schema will require some enhancements, as there are additional fields needed beyond the current setup. Ideal Skills: - Proficiency in Go - Expertise in GraphQL - Experience with backend restructuring - Ability to modify and enhance existing schemas - Familiarity with implementing new fields and relationships in a schema.
