Summary
👤
Senior🎓
Top SchoolJeremy Dehaan is an embedded software engineer with 13 years of experience, currently building embedded systems at Google out of Kirkland, WA. He graduated from the University of Washington Bothell with a strong academic record (3.85 GPA) and brings a practical blend of embedded systems, backend work, and tooling from roles at Verathon and internships at Alaska Airlines. Jeremy has made notable open-source contributions to the D language compilers (dmd and ldc), where he redesigned garbage collection interfaces and implemented swappable and manual GC strategies—work that touches core memory-management infrastructure. He combines production-focused engineering with research and prototyping experience from Google Summer of Code and complements his technical depth with hands-on operational and R&D roles in small businesses. Known for clear documentation and careful refactors, he excels at making low-level systems more modular and maintainable.

The LLVM-based D Compiler.
Role in this project:Back-end Developer
Back-end DeveloperContributions:9 commits, 1 comment in 5 years 5 months
Contributions summary:Jeremy focused on enhancing the garbage collection (GC) system for the D compiler, specifically enabling swappable GC implementations. They modified the GC structure, implemented a new manual memory management approach, and updated the GC interface. Furthermore, they added documentation to the GC struct and performed several renaming operations for improved clarity within the GC proxy system. These changes involved core aspects of memory management within the compiler.
