Vyacheslav Chigrin
Worked on runtime reliability and performance in C and Python, focusing on WebAssembly and system programming. In emscripten-core/emscripten, addressed a build-time issue by providing a weak implementation of the __throw_exception_with_stack_trace symbol for standalone WASM builds, adding regression tests to ensure future stability. In bytecodealliance/wasm-micro-runtime, optimized multithreaded native calls by relocating the exception lock to the ModuleInstance data structure, reducing overhead and updating versioning for compatibility. Enhanced runtime safety by applying NO_SANITIZE_ADDRESS for stack overflow detection under AddressSanitizer. Demonstrated strengths in debugging, build systems, and multithreading, delivering targeted improvements to runtime robustness and performance.

Mar 1, 2026Month: 2026-03 — Deliveries focused on performance optimization and runtime reliability in wasm-micro-runtime. Key outcomes include moving the exception lock to the ModuleInstance data structure to reduce overhead for multithreaded native calls, updating AOT_CURRENT_VERSION to reflect this architectural change, and implementing ASAN-safe stack overflow detection by applying NO_SANITIZE_ADDRESS to avoid conflicts with ASAN local variables. These changes improve throughput for native-call-heavy workloads, strengthen build reliability under sanitizers, and demonstrate proficiency in concurrency, versioning, and memory-safety tooling.
