Summary
🤩
Rockstar🎓
Top SchoolLouise Berglund is a Lead Software Engineer at Neo4j with nine years of experience building and improving graph database features, particularly around Cypher query processing and spatial indexing. She combines a strong theoretical background (MSc in Engineering Mathematics) with hands-on backend work, contributing notable open-source improvements to Neo4j projects like APOC and the Spatial library (including a Hilbert space-filling curve implementation). Known for meticulous refactoring, security-driven dependency upgrades, and test fixes, she cares about robustness and maintainability as much as new features. Beyond coding, Louise is passionate about mathematical problem solving, technical writing, and teaching, and has a track record of organizing events and lectures through roles like board member of Pink Programming. Based in Malmö, Sweden, she brings both deep domain expertise in graph databases and a knack for turning complex algorithms into reliable production systems.
