Summary
🤩
Rockstar🎓
Top SchoolVictor Campos is a Staff Software Engineer based in Cambridge with 12 years of experience specializing in compilers, programming languages and low-level systems, blending academic rigor (MSc focused on compilers) with production-facing work at Arm and Cadence. He leads Arm's compiler support for M-profile architectures and serves as Editor-in-Chief for the Arm C Language Extensions, while frequently contributing backend fixes to the high-profile llvm/llvm-project—notably ARM/Thumb2 instruction and compiler-rt support. His track record includes impactful compiler analyses (value range propagation, memory-placement optimizations) that yielded measurable speedups and a 90% reduction in memory bugs through AddressSanitizer deployment. Comfortable authoring both specification-level documents and C++ code, he combines deep algorithmic knowledge with practical delivery across industry and research settings. A history of top academic selection and internships in Silicon Valley underscore his consistent high performance and curiosity-driven problem solving.
