Summary
🤩
RockstarBrad Roberts is a seasoned software engineer with 21 years of experience, known for deep back-end and compiler work and now enjoying a self-styled "Chief Laidback Officer" role in Bellevue. He spent 14 years as a Principal SDE at Amazon and earlier held engineering and leadership roles across database and systems companies, bringing strong production and project leadership chops. Brad is an active open-source contributor to the D programming ecosystem, with notable contributions to Phobos (the D standard library) and LDC (the LLVM-based D compiler), including Unicode support, type-casting utilities, and backend refactors. His blend of systems-level compiler knowledge and long-term production experience makes him especially adept at improving core libraries and build systems—work that often happens quietly but has outsized impact on developer tooling.
