Grant Duncan Grant first became familiar with Neo4j when he started working for Cambridge Intelligence, where he found the tool's documentation and Cypher query language extremely user-friendly. He has since been involved in several projects using the database, including a company mapping project that utilizes Neo4j to determine where certain failures within large conglomerates originate, as well as a project analyzing online world trade network data to identify relationships between countries' biggest trade partners. Grant recommends the online Neo4j development course for those looking to learn more about the platform and praises its ease of use, even for those without prior experience with graph databases. He also notes that Neo4j is a great tool for working with Cambridge's network visualization tool KeyLines, and encourages others to share their own Neo4j projects in future 5-Minute Interviews.
