Benji Smith
Engineer at Disbelief
Greater Boston United States
Summary
👤
SeniorBenji Smith is an engineer with 11 years of C++ and low-level systems experience focused on computer vision, graphics, and game-engine design. He has shipped AR and vision tooling for mobile platforms at Escher Reality and Niantic and now builds software at Disbelief, blending performance-conscious engineering with practical product needs. His contributions to the LLVM project—expanding the C API for atomic operations and new instruction builders—reflect a deep comfort with compiler and low-level APIs that few gameplay-focused engineers cultivate. Benji pairs object-oriented design sensibilities with hands-on optimization work, making him equally at home prototyping algorithms and hardening them for real-time use. Based in Greater Boston, he brings a developer-first approach to SDK and engine problems, often surfacing cross-disciplinary insights between graphics, vision, and systems.

Contributions summary:Benji primarily contributed to the C API of the LLVM project, adding features and functionality related to atomic memory operations and other core instruction behaviors. Their work included expanding the C API to support new atomic operations like `uinc_wrap`, `udec_wrap`, `usub_cond`, and `usub_sat`. They also added accessors and builders for new instruction types such as `CallBr`, along with functions for handling target extension types and no-wrap flags for GEP instructions. These changes increased the API's coverage and functionality.
