Hi 👋
I would love to work on this issue: “Add Leaderboard Caching Strategy.”
I have experience implementing caching strategies to improve performance and reduce unnecessary database load. I can introduce an efficient caching layer (e.g., in-memory or Redis-based), define proper cache invalidation rules, and ensure data consistency for leaderboard updates.
My focus will be on performance, scalability, and clean integration with the existing architecture.
Happy to take this on. Thanks
