## Apollo Graph Developer - Associate

As you work your way through the four required tutorials, you will be creating a real-world application called
`Catstronauts`.

This project consists of a frontend client built with _TypeScript_ and _React_, alongside a backend server that utilizes
_Node.js_ as its runtime environment and [Apollo Server](https://www.apollographql.com/docs/apollo-server) as a
standalone, spec-compliant GraphQL server.

## Certification exam

- 31 multiple choice questions
- 25 correct answers required to pass

I achieved success in my test, making only a single error.

This outcome highlights the effectiveness of the course, which comprehensively addresses all relevant material,
equipping me with the confidence to approach the exam calmly.

## Graph Developer - Professional

Well, now the next step is to gain a deeper knowledge of GraphQL and
get [Graph Developer - Professional](https://www.apollographql.com/tutorials/certifications/apollo-graph-professional)
certification.

> Developers who obtain this certification demonstrate strong familiarity with Apollo Federation concepts. They can
> apply those concepts to build a federated supergraph or move an existing monolithic graph to federation.

I really commend the [Raphael Terrier](https://www.linkedin.com/in/raphaelterrier/)
