The semantic layer
that makes AI reliable.

I build formal ontologies, governed taxonomies, and knowledge graphs for enterprise AI systems in finance, government, and regulated industries.

Per governed term

AI agents hallucinate because
the knowledge layer is missing.

The teams building AI in finance, healthcare, and regulated industries are moving fast — but the domain knowledge underneath is informal, inconsistent, or absent. Terms like "non-performing loan" or "beneficial owner" mean specific, legally significant things. A model that doesn't know that is a liability.

I close that gap with formal ontologies, governed taxonomies, and semantic data models that give AI systems the structured domain knowledge they need to reason reliably — not just generate plausibly.

What I build

01 /

Knowledge Graph Design

Domain-specific knowledge graphs built on OWL, SKOS, and RDF. Deployable in Neo4j or triple stores, connected to your RAG pipeline or agentic architecture.

02 /

Ontology & Taxonomy Engineering

Formal models aligned to FIBO, HL7, and government standards. Business glossaries and controlled vocabularies with governance built in from the start.

03 /

AI Grounding & Metadata Governance

Semantic layers that reduce hallucination and support compliance in regulated industries. Built to govern, not just describe.

Featured work

A complete banking domain semantic layer — built to ground enterprise AI agents in formal, governed financial domain knowledge.

Banking Domain

Financial Domain Semantic Layer

FIBO-aligned taxonomy with 134 governed terms, OWL ontology in Turtle syntax, and a Neo4j knowledge graph with synthetic AML/SAR scenario and 7 analytical Cypher queries. Designed to integrate with data catalog platforms and RAG pipelines.
