PROFILE

Marcin Kolny

Worked on enhancing the wasm-micro-runtime and rust-lang/rust repositories by delivering features focused on runtime compatibility, performance, and build reliability. Implemented targeted error messaging for WebAssembly reference type incompatibilities, updated build scripts to support the latest Rust toolchains, and integrated SIMD acceleration into the fast interpreter using Rust and C. Refactored build processes to use Python virtual environments, ensuring isolated and reproducible builds across platforms. Expanded maintainership documentation for the wasm32-wasip1 target and standardized build practices to reduce dependency conflicts. The work emphasized robust error handling, environment management, and cross-platform support, contributing to improved developer experience and CI stability.

January 2025: Delivered a targeted error message enhancement for WebAssembly Reference Types incompatibility in wasm-micro-runtime. The change clarifies when a module uses reference types but the runtime was compiled without support and provides actionable steps to resolve. This reduces user confusion, lowers support load, and improves developer experience by aligning error messaging with runtime feature support.
