Top SchoolIsaac Brodsky is a seasoned geospatial engineering leader and founder with 12 years of experience building scalable backend and data systems from startup to enterprise. As Co-Founder & CTO of Fused and previously Co-Founder & COO of Unfolded (now part of Foursquare), he architects next-generation geospatial analytics and visualization platforms used for large-scale market optimization. At Uber he led the H3 project—an influential open-source hexagonal geospatial indexing system—contributing robust build, testing, and cross-platform automation improvements that keep H3 production-ready. He combines hands-on systems work (Java, Spark, Kafka, Elasticsearch) with product-minded leadership, and is known for digging into CI/build subtleties that quietly prevent outages. Based in the San Francisco Bay Area, he brings entrepreneurial grit and a practical focus on reliable, testable infrastructure for spatial data.
