Senior🎓
Top SchoolDafydd Pearson is a Full Stack Developer with nine years' experience specialising in cloud-native geospatial applications and open-source, low-code civic tech. At Open Systems Lab he leads development of Plan✕—a rules-as-code planning platform—combining TypeScript, React, GraphQL, Postgres and Infrastructure as Code to deliver secure, accessible (WCAG 2.1 AA) systems. He has deep GIS expertise (OpenLayers, Ordnance Survey integrations, Geoserver/GDAL) and a track record of designing interoperable APIs and data standards that bridge legacy back-office systems. Equally comfortable mentoring teams and shipping production-grade features, he brings Scrum leadership and CI/testing discipline (Jest, Playwright, Cucumber) to balance short-term delivery with long-term maintainability. Based in Scotland, he’s committed to open source tooling for maps and planning, and often translates complex legislation into practical, auditable digital services.
