Mike Horn is a Principal Software Development Engineer with 16 years of experience building performant, user-focused web applications, currently shaping mapping and geospatial tooling at Esri. He led the redevelopment of Site Scan across acquisitions, migrating mapping stacks from Mapbox/Proj4js to ArcGIS and delivering browser-based measurement and analysis tools for drone imagery workflows. Comfortable balancing hands-on coding and team leadership, he has driven server-side rendering React launches and architected CMS and static-site systems earlier in his career. Based in San Francisco, he blends practical engineering with an appreciation for plants, the outdoors, and family life, which informs a pragmatic, sustainable approach to product design. Trained originally in genetics and plant biology at UC Berkeley, he brings a curiosity-driven perspective to mapping and spatial problems that isn’t obvious from his software roles alone.
