Summary
🤩
Rockstar🎓
Top SchoolChris De Graaf is a Site Reliability Engineer based in Halifax, Nova Scotia with a decade of hands-on experience building reliable infrastructure and developer tooling. He combines SRE pragmatism at Beacon Biosignals with deep open-source contributions to the Julia ecosystem—helping build cross-platform binary packaging (Yggdrasil), package templates, and core HTTP and terminal libraries. His background includes research software engineering at MIT and automation of CI/CD for scientific tutorials, reflecting a mix of production operations, build engineering, and reproducible research. Chris often operates behind the scenes—improving build systems, package reproducibility, and WebSocket robustness—skills that rarely show up on a resume but materially reduce operational friction. Colleagues describe him as a quietly effective engineer who prefers to be reached outside GitHub, and who brings academic rigor to pragmatic SRE problems.
