Marc Simpson is an Associate Principal in Trust and Safety at Google with 14 years of cross-platform software engineering experience spanning systems-level C/C++ and interpreter work through modern Go and Python services. He combines deep backend expertise (including JVM/Spring, Hibernate, MongoDB) with practical data and automation skills used in ad-exchange tooling, predictive analytics, and large-scale log processing. An active systems hacker, he has contributed to the core Rebol interpreter—improving portability and low-level series/browse behavior—reflecting long-standing interest in language runtimes and embedded systems. Comfortable shipping full-stack products, Marc pairs production-grade engineering practices (CI, Agile, design patterns) with research-minded curiosity rooted in an MA in Linguistics, which informs his work on personalization, trust, and safety signals. Based in San Francisco, he brings a blend of strategic client-facing consulting and hands-on implementation to complex safety and infrastructure problems.

Contributions summary:Marc primarily contributed to the core Rebol interpreter, focusing on backend logic and system-level interactions. Their work included modifying the BROWSE function, implementing and optimizing its behavior across different operating systems (Mac OS X and POSIX). Furthermore, the user addressed potential issues with tuple division by implementing rounding and later refactoring to use an internal rounding implementation for improved portability. Finally, the user improved the functionality of binary series creation to avoid unintended side effects.
Boron is a scripting language similar to Rebol. The interpreter is a C library which may be copied under the terms of the LGPLv3. (Mirror of: git://git.code.sf.net/p/urlan/boron/code.)
