Summary
🤩
Rockstar🎓
Top SchoolNathan Lanza is a Staff Software Engineer based in Orlando with a decade of experience building and hardening compiler and debugger tooling at scale. At Meta he focuses on LLVM/Clang and LLDB, contributing cross-platform fixes such as AArch64 and ABS64 relocations, Swift runtime integration on Windows, and VSCode debugging improvements. His work spans low-level systems, JNI/native integrations for Android bytecode optimization (contributions to Facebook's Redex), and build-system/CMake refinements that keep complex toolchains reliable. Trained in theoretical and mathematical physics at the graduate level, he brings a rigorous, research-oriented approach to debugging intricate runtime and ABI issues. Colleagues rely on him to bridge QA, backend engineering, and platform-specific subtleties to deliver debuggers that work in heterogeneous environments.
