Summary
🤩
Rockstar🎓
Top SchoolFrancisco Liébana is a Software Development Engineer III with 13 years of experience building high-performance web systems and map rendering technologies, currently based in San Francisco and working at Amazon. He has deep expertise in front-end engineering, WebGL/OpenGL-based mapping (Tangram, carto.js) and performance optimization—having led a search-engine project and dramatically improved large-scale Postgres log ingestion at Auth0. Francisco combines systems-level tuning (partitioning, indexing, clustering) with UI-level refinements, and is comfortable across JavaScript, Rust, Java and SQL in production AWS environments. An active open-source contributor to well-known geospatial projects like CartoDB and Tangram, he’s equally driven by personal projects, LEGO building and learning a new language each year—evidence of his curiosity and attention to craft.
