Summary
👤
Senior🎓
Top SchoolDavid Murray is an analyst and network development engineer with 14 years of hands-on experience applying software and data science to urban mobility in Montreal. Currently at Exo, he develops transport network solutions and previously built platforms for mobility surveys and open-source network planning at Polytechnique Montréal. He pairs a Master's in Transportation Engineering with deep Python proficiency—contributing backend improvements to the widely used OSMnx library to enhance graph simplification and OSM export fidelity. His background spans machine learning for video/image classification, robotics automation, and Linux server administration, reflecting a pragmatic blend of research and production delivery. Comfortable moving between algorithmic work and web/platform engineering, he brings both academic rigor and practical system-building to transit planning problems. A less obvious strength is his history of improving geospatial tooling upstream in open source, helping tools used by planners and researchers interoperate more reliably.
