Rockstar🎓
Top SchoolFlorent Biville is a seasoned backend developer and database engineer with 13 years of experience, currently contributing to Neo4j while living in Cherbourg-en-Cotentin, Normandy. He has deep expertise in graph databases, compiler-like procedure development and database migration tooling, with notable open-source contributions to Neo4j APOC and the core Neo4j project as well as Liquibase. Comfortable across Java, Go and Python stacks, he pairs pragmatic engineering (TDD, refactoring, CI/CD) with a strong focus on code quality and test reliability. Florent is also an experienced trainer, mentor and conference speaker who has delivered workshops and talks on Neo4j, streams and microservices at international events. He blends hands-on implementation—adding features like composite index support and a Sørensen–Dice similarity function—with developer advocacy and teaching, helping teams adopt graph-centric architectures. A less obvious strength is his repeated role bridging product, training and open-source maintenance, which makes him effective at turning complex infrastructure work into usable developer tooling and curricula.
