Most GraphQL repositories teach you how to write resolvers.
Very few teach you what happens when your application gets real users.
So I built a production-grade GraphQL backend that goes beyond CRUD and explores the engineering problems most tutorials never touch.
Some of the challenges it solves:
→ How do you prevent the N+1 query problem?
→ How do GraphQL subscriptions work across multiple servers?
→ How do you invalidate JWTs without maintaining a blacklist?
→ Where should business logic actually live?
→ How do you structure a GraphQL codebase that doesn't become a mess after 6 months?
To answer those questions, I implemented:
• DataLoader for query batching
• Redis-backed Pub/Sub for scalable subscriptions
• JWT Auth + Role-Based Authorization
• Service & Repository Pattern
• Request-scoped Context Injection
• Rate Limiting
• Graceful Shutdown
• Prisma ORM
The biggest lesson?
GraphQL isn't the hard part.
Designing systems around GraphQL is.
If you've only seen tutorial-level GraphQL projects, this repo will show you what comes next.

Good morning guys.
Today's agenda implementing the ReAct paper, Plan and execute paper and the Reflection Paper with an easy-to-understand fashion just like my GraphQL repository, so that any beginner can level up their Agentic AI knowledge by studying my repo.
Shoot any questions

@RobGuerra90 Mostly AI infra, as that's where I am working on currently, but I am all in for low-level systems and scalable infrastructure, lots of experts here on X. Every day, new learning
