Top expert inScientific Computing and Data Science
Elliott De Andrade is a Research Software Engineer based in Toronto with 26 years of hands-on experience building and hardening scientific and systems software. He specializes in test automation, quality engineering, and backend systems, contributing substantial improvements to test suites and CI robustness across major projects like NumPy, pandas, GDAL and Matplotlib. Elliott pairs deep C/C++ memory-management fixes and build-system work (ninja, meson, libspatialindex) with pragmatic Python tooling and cross-version compatibility fixes (python-future, OpenKinect), making him comfortable across language and platform boundaries. He has a track record of improving developer experience—parameterizing tests, enabling parallel runs, and capturing command output for custom build targets—so projects scale more reliably. Active in prominent open-source ecosystems, his contributions often focus on the often-overlooked infrastructure that keeps scientific software trustworthy and reproducible.
