Top SchoolDehowe Feng is a Documentation Engineer at Meta with 11 years of software engineering experience, specializing in graph databases and Cypher query language features. Previously a backend developer at Bitnine, he contributed significant Cypher and agtype enhancements to open-source projects like Apache AGE and AgensGraph—adding list handling, regex operators, null property support, and CASE logic that improved query expressiveness and correctness. Based in San Francisco and trained in computer science at UC Davis, he blends low-level database internals with clear developer-facing documentation and tooling. Dehowe’s work often targets subtle correctness issues—such as chained union logic and label validation bugs—demonstrating a focus on reliability as well as functionality. He brings a practical mix of production-grade engineering and communication skills that help bridge core database development with developer adoption.

AgensGraph, a transactional graph database based on PostgreSQL
Role in this project:Back-end Developer
Back-end DeveloperContributions:33 commits, 16 PRs, 5 pushes in 1 year 4 months
Contributions summary:Dehowe primarily contributed to the implementation of Cypher language features within the AgensGraph database. Their work involved adding support for Cypher list literals, list concatenation, list access (indexing and slicing), and list predicate functions (all, any, none, single). They also implemented the =~ operator for regex matching and enabled the storage of null properties, showcasing a focus on expanding the Cypher query capabilities of the graph database.
