Summary
👤
Senior🎓
Top SchoolFraser Hutchison is a Senior Rust Engineer with 16 years of systems and backend experience, now based in Dalrymple, Scotland. He has deep expertise in Rust, C++, and CMake, and a strong track record improving performance and reliability in distributed and blockchain projects—most notably contributing to the Casper node and its upgrade testing, trie-store efficiency, and Wasm execution engine optimizations. Fraser has also worked on low-level networking and crypto libraries (including MaidSafe’s crust and sodiumoxide), pairing rigorous test automation with practical bug fixes and Rust upgrade migrations. A former Director of R&D who built CI, CMake build systems and cross-platform backend integrations, he combines hands-on coding with architecture and team leadership. Unusually for someone focused on Rust today, his roots in C++ and long-standing involvement in Byzantine-resilient protocols give him a rare blend of systems depth and distributed-systems pedigree.
