Summary
🤩
RockstarIngvar Stepanyan is a seasoned software engineer with 14 years of cross-platform systems and tooling experience, now based in the UK after moving from Ukraine. He specializes in low-level tooling, compilers, parsers and WebAssembly—acting as a WebAssembly consultant and contributing to flagship projects like Emscripten, wasm-bindgen, V8 tooling and the WebAssembly website. His open-source footprint spans languages and domains, from AST and parser work in Babel, Acorn and Estraverse to performance-sensitive contributions in quiche, rav1e and oxipng, and build automation improvements for React and Squoosh. Comfortable across front-end and back-end boundaries, he blends deep systems thinking (threading, serialization, ABI/string handling) with pragmatic developer tooling and test automation. Colleagues value his talent for untangling edge cases—whether in HTML tokenization, cross-platform path/encoding bugs, or safe LLVM bindings—making him a reliable engineer for hard, detail-heavy engineering problems.
