Explains how React error boundaries, route errors, safe fallbacks, logging, and recovery work together.
Explains capturing, targeting, bubbling, default behavior, and safe event delegation for dynamic interfaces.
Compares offset and keyset pagination for stable API lists, large tables, and user-facing result consistency.
Explains relational modeling, duplication, write consistency, read performance, and when denormalized data is justified.

Explains Redis memory pressure, eviction policies, key sizing, TTL discipline, and what happens when the cache is full.
Explains how an API behaves when Redis is unavailable and which cache usages can safely fall back.
Explains why application-level duplicate checks are not enough and how EF Core APIs map database constraints to friendly errors.
