Summary
🤩
Rockstar🎓
Top SchoolCarlos Seo is a Technical Lead with nearly two decades of experience driving open-source compiler and toolchain engineering, currently leading LLVM work and AI-driven compiler experiments at Linaro. He has deep CPU enablement expertise across POWER and Arm architectures, having delivered high-impact performance optimizations in glibc, Go, OpenBLAS and LLVM while at IBM and Arm. A prolific contributor to golang/go and LLVM, he implemented core runtime and atomic-operation improvements for ppc64x and added assembly support for VDSO and vector registers. He blends hands-on low-level development (assembly, ABI changes, intrinsics) with team leadership and product-focused delivery, having led global teams and reorganized R&D to boost velocity. Notably, he helped bring Morello/CHERI support into public toolchains and maintained the Go compiler ports for POWER, demonstrating rare cross-architecture compiler portability skills. Based in Greater São Paulo, he pairs an M.S. in Electrical Engineering with a track record of patent-backed innovation and measurable performance wins for enterprise processors.
