San Francisco, California, United States
Summary
🤩
Rockstar🎓
Top SchoolPaul Kirth is a software engineer with 13 years of experience specializing in compiler toolchains, currently advancing LLVM for Fuchsia at Google with a focus on compiler-aided security, sanitizers, and program analysis. He holds a PhD in System Security from UC Irvine, where his dissertation produced compiler-driven techniques for strong intra-process isolation between memory-safe and unsafe components. Paul is an active contributor to the upstream llvm-project—especially RISC-V and Android target work—authoring APIs, tests, diagnostics, and documentation that impact a widely used open-source compiler. He combines deep research experience with practical engineering, having built LLVM features like PGO-driven diagnostics and runtime behavior injection during earlier internships. Based in San Francisco, he brings a pragmatic security lens to performance and tooling, often leveraging compiler instrumentation to turn program traces into hardened, efficient runtimes. An interesting detail: his background spans civil engineering and even novel writing, reflecting a blend of analytical rigor and creative communication.

Back-end Developer
Back-end DeveloperContributions:1116 reviews, 4 commits, 371 PRs in 6 days
Contributions summary:Paul primarily contributed to the LLVM project, specifically focusing on the RISC-V architecture. Their work involved implementing new APIs, modifying existing code, and adding tests related to Android targets and atomic ABI attributes for the RISC-V architecture. Furthermore, the user made changes to the compiler's internal logic, such as updating branch weight metadata and extending the functionality related to atomic operations. They also updated documentation and fixed style guide violations in HTML generation.
