Jorge Alejandro Pichardo Cabrera
Worked on the leil-io/saunafs repository, delivering core backend features and reliability improvements over four months. Developed load-aware garbage collection with dynamic throttling and parallelized trash removal to optimize disk I/O and accelerate space reclamation. Enhanced observability by adding real-time GC deletion metrics and space reclamation monitoring to the chunkserver dashboard. Introduced runtime plugin reloading to reduce downtime and tuned cache management for improved write throughput. Stabilized rebalancing logic and master restart handling, refining CI/CD pipelines and test automation to ensure robust deployments. Leveraged C++, concurrent programming, and system programming skills to address performance, monitoring, and operational challenges in distributed file systems.

Mar 1, 2026March 2026: Delivered performance-focused GC optimizations and enhanced observability for leil-io/saunafs. Key changes include a load-aware garbage collector that throttles expiration deletions based on disk throughput, parallelized trash removal across disks, and configurable GC purge workers, plus new monitoring of space reclamation. These changes reduce IO contention during large deletion storms, accelerate space reclaim, and provide precise reclamation metrics for capacity planning. The work demonstrates strong backend performance engineering, multithreading, and observability enhancements with measurable business impact.

Feb 1, 2026February 2026 monthly summary for leil-io/saunafs: Implemented GC deletions per minute tracking in the chunkserver CGI chart to enhance observability, aiding testing and reliability of GC-related workflows. This feature adds visibility into deletions when chunks are moved to trash and subsequently purged by GC, enabling better monitoring and capacity planning.
