User: Id, name
Services: id, service_name
Categories: id, service_id, category_name

Relationships
User has many Categories
Service has many categories
category can have one service
category belongs to many users

$result = Professional::where('user_id’,’=‘,54)->get();

    "id": 1,
    "user_id": 54,
    "service_id": 8,

    "id": 2,
    "user_id": 54,
    "service_id": 10,
    "category_id": 23
