Worked on Migorithm/duva over three months, delivering eight features and addressing core reliability and performance challenges in Rust. Developed cross-platform terminal UI improvements by migrating to crossterm, enhancing Windows compatibility and robustly handling line endings. Refactored cache management by implementing a modular LRU cache with capacity-based eviction and comprehensive tests, using Rust’s memory-safe design and benchmarking tools like Criterion. Improved test infrastructure by introducing pre-built binaries and optimizing build configurations, reducing CI friction. Enhanced observability with detailed logging and tracing, and resolved critical bugs such as use-after-free in cache logic, resulting in more predictable, maintainable, and performant backend systems.

Jun 1, 2025June 2025: Migorithm/duva delivered key features and stability improvements with measurable business impact. Key features: CacheDb reliability and performance enhancements, including memory-safety improvements (private visibility in tests), reintroduction of an efficient LRU cache, and added benchmarks comparing safe RCN vs raw pointer-based cache data structures. Test infrastructure optimization enabling pre-built binaries for tests (duva and duva-client) built once via sync::Once to speed startup. Major bugs fixed: use-after-free in tail removal and maintenance of the key map, plus visibility-related test refactor to improve test reliability. Overall impact: more reliable cache behavior, faster CI/test cycles, and clearer performance signals, enabling more predictable performance and faster iteration. Technologies/skills demonstrated: memory-safe Rust design, cache data structures (LRU), benchmarking, and CI/test infrastructure automation. Commits highlights: 9ea7f1fcb9643967b5a63bf999e15bfa4785ab5b (change cache_db validate visibility), 64bfa45f1d887b035238b5135e4541fc088783a1 (fix: cache_db uaf), d6cff9f0010eed3439d86f8883481a8466d52d6c (benchmark cache db), 6695e2938fe0de7b481a4f9657da241065c41e9f (use prebuilt binaries for tests).

19 Commits • 4 Features
May 1, 2025May 2025 monthly summary for Migorithm/duva: Delivered a focused set of performance, reliability, and observability improvements that strengthen core data handling and operational insight. Implemented a Performance Benchmarking Framework with Criterion, including a base benchmark and a dedicated module to measure query serialization performance. Refactored and expanded CacheDb into its own module with a full-featured LRU cache, capacity-based eviction, an Entry API, and thorough tests. Streamlined the test harness and build configuration to reduce test friction and remove unused CLI/vscode settings. Fixed LLDB debugger integration by ensuring duva-client builds and launches are handled separately to avoid misreading output as JSON. Added extensive observability through critical-path tracing and verbose logs to improve debugging and monitoring. Overall, 19 commits across 5 work items, delivering tangible business value through faster iteration, improved reliability, and stronger data-management capabilities.
