Summary
🤩
Rockstar🎓
Top SchoolStephen Woodbridge is a veteran geospatial engineer and entrepreneur with over two decades building mapping, geocoding, routing and GIS solutions through his company iMaptools and long-standing contributions to the Open Source Geospatial Foundation. He combines deep systems-level expertise in C/C++, Python and spatial databases (PostgreSQL/PostGIS, pgRouting) with practical product delivery experience—designing turnkey GIS stacks that scaled to hundreds of millions of map draws annually. As a charter OSGeo member and active back-end developer on projects like pgRouting, he has made substantive algorithmic contributions to turn-restricted shortest path and core routing logic. His background spans hands-on engineering, infrastructure automation, and leadership roles where he bridged DBAs, cartographers and developers to move complex geospatial systems to production. Now retired and based in Chelmsford, MA, he remains a resource for former clients and the open-source community, offering referrals and occasional technical help.
