Worked on the google/syzkaller repository to enhance kernel fuzzing infrastructure, focusing on robust feature delivery and maintainability. Developed a corpus-driven kernel behavior comparison mode, enabling deterministic testing across multiple kernel versions and detailed mismatch logging. Refactored core fuzzing logic into modular helpers for improved readability and long-term support. Integrated CrashStore into the syz-verifier HTTP server, centralizing crash report management and streamlining corpus-path handling. Addressed concurrency issues and improved observability through enhanced HTTP server instrumentation. Leveraged Go, concurrent programming, and backend development skills to deliver more reliable fuzz testing, clearer diagnostics, and faster debugging for kernel compatibility validation.

Jan 1, 2026January 2026 focused on delivering a robust, corpus-driven kernel behavior comparison workflow in google/syzkaller and improving code maintainability through targeted refactoring. Delivered a kernel behavior comparison mode that uses a pre-existing corpus to test program execution across multiple kernel versions, logging per-call syscall differences and full program sequences. Refactored the fuzzing loop into focused helpers (fetchNextRequest, isDistributableRequest, buildRequestCopies, dispatchAndCollect) to improve readability without changing behavior. Transformed syz-verifier from a coverage-discovery fuzzer into a kernel-comparison tool that consumes corpus.db via -corpus, runs across kernels in parallel, and logs mismatches with comprehensive context. Result: more deterministic cross-version testing, faster feedback, and easier long-term maintenance, delivering tangible business value by improving kernel compatibility validation while reducing manual debugging time.
