Timothy Clem
Software Engineer at GitHub
San Francisco, California, United States
Summary
🤩
RockstarTimothy Clem is a software engineer in San Francisco with about 15 years of experience and a GitHub engineer since 2011. He pairs low-level systems work—contributions to core Git libraries (libgit2, LibGit2Sharp) and parser/runtime projects (tree-sitter, semantic)—with higher-level framework improvements in ReactiveUI and Rails view components. His open-source commits demonstrate a pragmatic focus on interoperability and robustness: fixing cross-platform build issues, tightening tests and edge-case handling, and refining reactive collection behavior and observability. Comfortable across back-end, compiler/runtime, and .NET interop layers, he brings production-grade tooling instincts and a knack for turning tricky infra details into stable developer-facing APIs.
