API & Backend Engineering

Ship production-grade APIs backed by solid storage and sync fundamentals.

From REST and GraphQL contract design down to SQL query internals, then into the real-time world of CRDTs and operational transforms. The sequence mirrors how a backend feature actually travels: API surface -> data layer -> multi-client synchronization.
