GraphQL Federation promises a unified API across microservices teams. Here is what the production reality looks like: Apollo Router, subgraph architecture, entity resolution patterns, and how to avoid the distributed monolith trap.
gRPC is not just 'faster REST'. It's a fundamentally different communication model that changes how you design APIs, handle streaming, and think about service contracts. Here's what you actually need to know.
What makes an API developer-friendly: naming conventions, error handling, pagination, versioning, docs, and the design principles that separate great APIs from painful ones.
HTTP methods explained with real-world examples. GET, POST, PUT, PATCH, DELETE, plus HEAD and OPTIONS. When to use each, idempotency, and common mistakes.
GraphQL vs REST compared honestly: architecture differences, real performance trade-offs, and a practical decision framework for choosing between them.
Practical deep dives on infrastructure, security, and scaling. No spam, no fluff.
