Omar Habra
Omar Habra — AI infrastructure and compiler engineer in San Francisco. Swift/Clang compiler at Apple (2020–22), LLVM for RISC-V at SiFive (2022–23). Since 2023: production AI systems for clients. Since 2026: founder of DiffSwarm (AI code review) and RedlineAI (AI contract review for legal teams). Open source: merged Swift C++ interop PRs; two Tenstorrent model-port bounties accepted. Grew up in Damascus; B.S. Computer Engineering, San José State, 2020.
Experience
- Apple, Software Engineer (2020–22): Swift ↔ C++ interoperability. Worked on Swift's C++ interoperability, which lets Swift call C++ directly and shipped in Xcode. My merged change turns C++ getX()/setX() pairs into Swift properties; it still underpins Swift's SWIFT_COMPUTED_PROPERTY. Also fixed arm64 ABI and backend issues during the move to Apple Silicon.
- SiFive, Senior Software Engineer (2022–23): LLVM / RISC-V vector codegen. Tuned how LLVM vectorizes code for SiFive's RISC-V vector cores, boosting performance for customer RISC-V silicon, and built the benchmarks and CI that caught compiler regressions before they reached customers.
- Independent, Founder & AI infrastructure engineer (2023–now): Two AI products, and AI systems for clients. Since 2023 I have built production AI systems for clients. In 2026 I founded DiffSwarm, AI code review that runs in CI, and RedlineAI, contract review for legal teams on the Mac. Both are live with paid plans.
Selected work
- Tenstorrent TT-Metal: Two Tenstorrent model-port bounties, completed and accepted.
- DiffSwarm: AI code review that catches bugs before merge.
- RedlineAI: AI contract review for legal teams, on the Mac.
