Rockstar🎓
Top SchoolImre Samu is an owner and seasoned geospatial software engineer with 11 years of experience building and maintaining data pipelines, PostGIS/Postgres tooling, and Docker-based deployments from Budapest. He contributes regularly to prominent open-source mapping projects—most notably Imposm3, PostGIS Docker images, Natural Earth, and OpenMapTiles—focusing on ETL, spatial indexing, topology, and regex-driven filtering for OSM ingestion. His work blends backend engineering, database optimization, and DevOps automation, including cross-platform image migration and build refactors that keep maps and vector tiles up-to-date. Pragmatic and detail-oriented, he brings a strong grounding in spatial data modeling and topology (and even Julia experimentation) that helps translate messy real-world geographic data into reliable, production-ready databases.
