Top SchoolDerek Cresswell is a software engineer with 7 years of experience building developer-facing tooling and performance-critical systems, currently a Member of Technical Staff at Cerebras after a tenure as SDE II at AMD. He specializes in modernizing build and driver ecosystems—leading migrations from Make to CMake, refactoring kernel-mode drivers into modern C++, and cutting compile and CI times by an order of magnitude. His academic background in OSes, compilers, and language paradigms from the University of Toronto informs work on compiler-level ML optimizations and an educational Rust OS threading subsystem. Outside of work he contributes to C++ tooling such as the dbg-macro project, adding nuanced support for pairs and binary printing, and prefers shipping internal, production-grade engineering over public GitHub visibility. Known for pragmatic cross-team collaboration, he combines systems-level rigor with a lifelong curiosity that began at age 13.
