Rockstar🎓
Top SchoolCraig Taverner is a Principal Software Engineer and entrepreneur with 16+ years building database, search and GIS systems, now focusing on geo-spatial analytics at Elastic. He co-founded AmanziTel, pioneered smartphone-enabled customer experience management, and later led the Cypher query engine team at Neo4j before working on cloud orchestration for Aura. His work spans core database internals, spatial libraries and vector-tile/GeoJSON support in Elasticsearch, reflecting deep hands-on expertise in graph databases and spatial data. Comfortable moving between startups and large enterprises across Europe, Asia and the US, he combines research-grade scientific training (MSc and PhD-level study in theoretical chemistry) with practical product and engineering leadership. A long-time open-source contributor, Craig has made notable commits to Neo4j core and Neo4j Spatial as well as Elasticsearch, often touching low-level runtime and parsing logic. He’s equally at home designing algorithms, shipping production systems and mentoring teams that solve hard spatial and telecoms problems.

Neo4j Spatial is a library of utilities for Neo4j that faciliates the enabling of spatial operations on data. In particular you can add spatial indexes to already located data, and perform spatial operations on the data like searching for data within specified regions or within a specified distance of a point of interest.
