Senior Knowledge Graph Engineer at Elevait who built an ontology engineering practice that cut modeling time from two months to three weeks.

Germany
Message

At Elevait, I built an iterative ontology engineering practice that cut data-modeling time from about two months to three weeks and accelerated customer onboarding. I designed modular semantic models for energy, finance, and construction, and led knowledge graph construction across customer instances.

I also developed dm-foundry, a Python toolkit for ontology releases, RDF ingestion, validation, and GraphDB deployments. Extending quality gates with SHACL business rules helped drive silent pipeline failures to zero.

At NEC Laboratories Europe, I contributed to temporal knowledge graph forecasting research, filed three patents, and built entity-linking pipelines for an operational knowledge graph used by law-enforcement agencies. Across my work, I focus on semantic foundations that make AI outputs more reliable, traceable, and grounded.
