 | I'm a compiler engineer at Meta, working on size and PGO optimizations in LLVM. I'm Rust-curious and sometimes I tinker with low-level esp32 Rust projects. When I'm off the computer, I like biking and exploring San Francisco's green space. ellis [dot] hoag [at] gmail [dot] com iOS Compiler Engineer, PL&R @ Meta |
