Worked on the HPCC-Platform repository, focusing on system reliability, memory management, and code quality over five months. Delivered a new feature enabling jemalloc as a configurable memory allocator, improving performance and stability for large-scale deployments. Addressed five critical bugs, including fixes for deployment cleanup, configuration handling, resource leaks, and cache offset calculations, each enhancing platform robustness and data integrity. Applied C++, CMake, and Shell scripting to implement safe error handling, static analysis compliance, and optimized cache management. The work emphasized maintainability and production readiness, with careful attention to deployment safety, memory profiling, and adherence to HPCC coding standards throughout.

Feb 1, 2026February 2026 (Month: 2026-02) - HPCC-Platform: Delivered a critical bug fix in the Roxie cache offset calculation, ensuring proper casting of cacheKey and preventing data integrity issues during cache operations. This aligns with HPCC-35833 and was implemented and committed (68ba0c550b01c1445c3d418ff6b5294566e95ef0). The change enhances cache reliability, reduces data corruption risk under load, and contributes to overall platform stability. Demonstrated debugging of complex cache logic, type casting, and patch delivery within HPCC coding standards.
