SUMMARY

Ontologist and Semantic Architect with 10+ years building RDF/OWL ontologies, knowledge graphs,

and semantic metadata systems for complex enterprise environments. Deep hands-on experience with

W3C standards (SPARQL, OWL, SKOS, RDFS), graph databases (GraphDB Ontotext, Neo4j), and

enterprise taxonomy management platforms (TOMS). Track record of enabling cross-system data

integration, semantic search, and personalization at scale across siloed enterprise content ecosystems.

Strong foundation in NLP-driven metadata extraction, information architecture, and content

management strategy. Proven ability to translate ambiguous business requirements into structured,

intuitive ontologies that drive analytics, discovery, and customer experience outcomes.
