Patrick Steinhardt
Software Engineer at GitLab Inc.
Berlin, Germany
Summary
🤩
RockstarPatrick Steinhardt is a seasoned software engineer based in Berlin with 15 years of experience building and hardening low-level and backend systems. He contributes actively to high-profile open-source projects such as Git and libgit2 bindings (pygit2, git2go), improving submodule handling, ref storage, and memory safety—work that directly impacts widely used developer tooling. At GitLab he brings deep systems and build-tool expertise honed through contributions to util-linux, Meson, and a keyboard-driven browser (vimb), demonstrating comfort across C, Go, and Python ecosystems. Patrick combines pragmatic engineering—fixing panics, memory leaks, and test performance—with attention to long-term maintainability, and he’s as likely to refactor build integrations as to expose hardware-acceleration toggles. A pragmatic problem-solver, he tends to surface subtle, correctness-first fixes that quietly improve stability for thousands of users.
