Worked on AFLplusplus/LibAFL to enhance observability and stability for fuzzing workloads by refactoring Prometheus metrics, enabling both global and per-client statistics through new APIs and improved monitoring logic. Addressed a brk syscall handling bug in the QEMU integration, introducing an API to manage heap growth and shrinkage, which improved diagnostics and reliability. In subsequent work, focused on stabilizing snapshot-based fuzzing by refining memory management during heap shrink events, remapping memory pages to preserve data integrity and adjusting mprotect permissions. Utilized C and Rust, applying expertise in system programming, concurrency, and memory management to deliver robust, maintainable improvements.
