Summary
🤩
Rockstar🎓
Top SchoolRaúl Marín is a systems-focused software engineer with 14 years' experience building and hardening high-performance data and geospatial infrastructure. He has deep hands-on expertise with ClickHouse, PostGIS/PostgreSQL, Mapnik and the broader geospatial OSS stack, contributing upstream fixes and features while shaping production architectures at Tinybird and CARTO. Raúl bridges low-level C/C++ memory- and concurrency-hardening with pragmatic platform work—automating tests, designing scalable services, and enabling cloud-native tiling via WebAssembly and BigQuery UDFs. A core PostGIS contributor and PSC member, he regularly improves stability in major projects like GDAL, GEOS and Mapnik, and has a habit of shipping fixes upstream rather than fork-and-fix. Based in Sigüenza, Spain, he combines deep debugging instincts with ops skills (CI, build systems, server administration), making him equally comfortable in perf hotspots and deployment pipelines.
