Worked on enhancing cache performance and reliability in the kamilkisiela/graphql-hive repository by upgrading the Tiny-LRU dependency to its latest version. This targeted feature improved cache efficiency across services, aiming to reduce latency and support scalable workloads. The approach centered on careful dependency management and cache optimization, with changes implemented in TypeScript to ensure maintainability and traceability. All updates were delivered through precise, well-documented commits, aligning with changelog standards to facilitate future audits and rollbacks. No major bugs were reported or addressed during this period, reflecting a focused effort on proactive performance improvements rather than reactive maintenance or bug fixing.
