Kirtesh maps 11 backend concepts

- Kirtesh published an 11‑item thread of backend concepts for 2026 covering event‑driven architecture, caching, sharding, rate limiting, distributed tracing, CQRS, Saga patterns, versioning and graceful shutdown. - The thread explicitly ties these ideas to real operational needs like scaling, consistency and observability for modern distributed services. - It’s framed as a topical skills map for engineers who need to pick practical system design priorities.
