À propos de ce service

Traduction automatique

Si vous travaillez avec des relations complexes, des données connectées ou des systèmes basés sur des graphes, Neo4j est puissant mais seulement lorsqu'il est modélisé et interrogé correctement.


J'aide les fondateurs, ingénieurs et équipes de données à concevoir, déboguer et optimiser les bases de données Neo4j pour qu'elles soient :

  • rapides
  • extensibles
  • faciles à comprendre
  • prêtes pour la production


Je ne me limite pas à écrire des Cypher.

Je vous aide à penser en graphes.
