👤
SeniorMatt Walker is a seasoned geospatial technologist with 15 years' experience building web-centric spatial tools and advocating for open software, standards and data. Based in Wyre Forest, England, he combines front-end UI finesse in JavaScript and Clojure with backend work in Python and SQL, contributing to prominent projects like OpenLayers and MapProxy. His open-source contributions span UX improvements, robust testing, and image-processing middleware—examples include enhancing OpenLayers' layer switcher and adding WSGI image post-processing to MapProxy. At Astun Technology he applies this full-stack geospatial expertise to production systems, while his earlier role as a technical director reflects long-standing product and delivery ownership. Known for pragmatic, standards-first solutions, he often surfaces subtle UX and interoperability fixes that improve real-world mapping workflows.

Role in this project:Back-end Developer
Back-end DeveloperContributions:3 reviews, 17 commits, 6 PRs in 7 years 10 months
Contributions summary:Matt primarily focused on enhancing the MapProxy's core functionality, particularly in the area of image processing and web service integration. Their work included adding support for WSGI middleware to allow image post-processing, ensuring correct handling of coverage intersections in tile rendering, and refactoring code to improve maintainability.
