Florian Hockmann
Software Engineer at GDATASoftwareAG
Summary
🤩
RockstarFlorian Hockmann is a software engineer with nine years of experience specializing in back-end systems, distributed graph databases, and automated malware analysis. Based in Germany, he contributes to prominent open-source graph projects such as Apache TinkerPop and JanusGraph, improving .NET driver serialization and GraphSON compatibility across storage backends like HBase and Cassandra. His work shows a strong focus on robustness and interoperability—handling tricky edge cases like null-value serialization and predicate support across GraphSON versions. Curious and detail-oriented, he blends systems-level database engineering with security-adjacent automation, making him fluent in both graph technology internals and practical tooling for analysis pipelines.
