PROFILE
Kostik Shtoyk
Kostik worked on stabilizing and maintaining the build system for the google/silifuzz repository, focusing on reproducible builds and robust fuzzing infrastructure. He addressed build configuration issues using Bazel and Starlark, improved binary logging for better debugging, and clarified code semantics by renaming key functions. Kostik also enhanced instruction set governance by banning disallowed instructions in the fuzzing runner, directly improving test safety and reliability. In addition, he fixed platform identification for Coffeelake CPUs, ensuring accurate instruction set detection and alignment with hardware capabilities. His work demonstrated depth in low-level systems programming, C++ development, and build system management throughout the project.

Nov 1, 2024November 2024 (google/silifuzz): Stabilized and maintained the build system, hardened the fuzzing runner against disallowed instructions, improved observability through binary log enhancements, and clarified code semantics with an upfront rename of is_deterministic() to is_allowed(). These efforts delivered more reliable builds, reduced debugging time, and clearer governance of allowed instructions, enabling faster iteration in fuzz testing and safer execution across environments.
