Worked on the category-labs/monad repository, focusing on memory management and cache performance in C++. Delivered two core features over two months, first migrating Node and Trie data structures to std::shared_ptr with pool-aware allocation to improve memory safety and runtime stability. Refactored ownership models and addressed destructor issues to reduce memory leaks and simplify lifetime management. Later, implemented a thread-safe clock-based cache eviction strategy, introducing the ClockReplacer class to balance usage frequency and recency under concurrent workloads. Emphasized concurrency, data structure optimization, and performance evaluation, validating changes with targeted tests to ensure robust, scalable behavior in long-running applications.

2 Commits • 1 Features
Jun 1, 2025Delivered a clock-based cache eviction strategy for category-labs/monad, introducing a thread-safe ClockReplacer and integrating it into existing cache layers. Implemented and executed tests to validate correctness and performance, with two commits: aeb7fd7a4207c055b066e78ac2592067aa835deb and ac8751a74b275bb80637266eb5dfc6438723dbb9. No critical bugs fixed this month; the focus was on a high-impact architectural improvement. Overall impact: improved memory management and cache performance by balancing usage frequency and recency, reducing memory pressure during peak workloads and enhancing scalability. Technologies/Skills demonstrated: concurrency-safe design, cache eviction algorithms, testing strategy, code instrumentation, performance evaluation.
