Worked on the vortex-data/vortex repository to address a runtime crash in patch_chunk decompression, specifically targeting index-out-of-bounds errors when slicing ALP arrays that do not align with chunk boundaries. Applied Rust to implement a robust end-bound calculation using saturating subtraction, ensuring memory safety and preventing overruns during mid-chunk decompression. Developed comprehensive unit and integration regression tests to validate the fix and maintain stability across patch-driven decompression workloads. All existing test suites, including vortex-array and vortex-alp, passed successfully. Demonstrated backend development and data processing expertise by documenting the root cause, outlining the testing plan, and integrating the solution through code review.
