Summary
🤩
Rockstar🎓
Top SchoolBert Maher is a compiler-focused software engineer with 13+ years building and optimizing compilers and performance tooling across domains from ML hardware (Glow, PyTorch/TorchScript, functorch, Triton) to mobile bytecode (ReDex) and binary translation (Transmeta/Intel MoonRun). He combines deep systems and computer-architecture knowledge with pragmatic profiling skills to squeeze cycles and reduce latency in real-world stacks, and has led compiler efforts at Facebook/Meta before joining Anthropic to focus on inference and performance. His open-source footprint includes substantive backend work on high-profile projects like PyTorch/functorch and Triton, adding eager compilation support and improving module compilation and caching. Bert’s contributions span both low-level memory- and layout-sensitive optimizations (HFSort, ProguardMap, Dex handling) and developer-facing build systems (Buck, PyTorch builder with LLVM integration). He holds advanced computer-science training from UT Austin (PhD/MS) and a BS from Yale, pairing research depth with long-term production impact. An underappreciated strength is his consistent ability to simplify configurations and tests while improving runtime efficiency, reflecting a taste for maintainable high-performance engineering.

A bytecode optimizer for Android apps
Role in this project:Back-end Developer
Back-end DeveloperContributions:2 releases, 189 commits, 4 PRs in 1 year 6 months
Contributions summary:Bert primarily contributed to the optimization of the Redex bytecode optimizer for Android applications. Their work involved fixing bugs related to argument handling, and memory safety concerns. Additionally, they improved the ProguardMap, and added code to manage and manipulate Dex files, including the handling of String and Type elements. The user also refactored the configuration handling process.
