Owned complete Spring Security + JWT implementation: built custom OncePerRequestFilter, token parsing/validation, UserDetailsService, and role-based authorization; implemented access/refresh token flow with stateless authentication across services.* Designed Kafka-based event pipeline for critical workflows with entity-key partitioning, idempotent consumers, retry/backoff handling, and DLQ setup to ensure safe processing under rebalances and failures.* Fixed multi-table data inconsistency by restructuring @Transactional boundaries and propagation; ensured atomic writes across service + event publish flow.* Optimized Hibernate/MySQL performance by eliminating N+1 queries, introducing projection-based reads, and adding composite indexes after analyzing execution plans.* Implemented Redis caching for permission/config reads with event-driven invalidation to maintain cache consistency across distributed instances.* Resolved high-concurrency update issues using optimistic locking (@Version) and retry-safe write flows, preventing stale overwrites and race-condition-driven corruption.
