Jiakai contributed to the google/syzkaller repository by expanding RISC-V KVM virtualization support, implementing features such as VCPU setup, guest memory management, and AIA device attribute integration to improve fuzzing and testing coverage on riscv64. He refactored SYZOS API call descriptors for maintainability, consolidated documentation, and enhanced onboarding clarity. His work involved deep kernel development in C and Go, with a focus on system programming, code organization, and version control. Jiakai also delivered operator development and benchmarking for FlagOpen/FlagGems, integrating a Triton-based Softplus activation function with performance validation, demonstrating a thorough and methodical engineering approach across projects.

February 2026: Delivered a focused feature refactor for SYZOS API call descriptors by consolidating common descriptors into a dedicated header (common_kvm_syzos.h). This improves maintainability, reduces duplication, and sets the foundation for safer future API surface changes. No major bugs fixed this month. Overall impact: cleaner code organization, easier future updates, and reduced risk of drift across SYZOS-related components. Technologies demonstrated: C/C++, header-based design, refactoring discipline, and Git-based change tracking (commit: ffa542879cca228b4e5f1bea6ba8de94dfacb90d).
