Summary
🤩
Rockstar🎓
Top SchoolTomáš Pohanka is a Geodata Specialist with 12 years of experience applying geoinformatics, databases and data engineering to map-making and spatial analytics. Currently at MapTiler, he focuses on improving data processing pipelines, database schemas and production tooling to deliver higher-quality vector tiles and more reliable tile generation. His PhD work on distributed geodatabases for sensor data underpins a strong research-to-production aptitude for handling large, messy spatial datasets. As an active contributor to the widely used OpenMapTiles project, he has optimized SQL, fixed invalid geometries and added nuanced features like protected areas and airport gates, improving both accuracy and performance. Comfortable across DevOps, backend and database engineering, he blends PostgreSQL/PostGIS expertise with Dockerized build systems and dataset curation. Fluent in turning academic insight into practical infrastructure, he quietly improves map quality at scale.
