OntoGuard: Production-Grade Ontology Firewall for AI Agents
Built and open-sourced a production-grade ontology firewall that validates AI agent actions against OWL-encoded business rules in real-time. Enforces role-based access control, amount constraints, time windows, and compliance rules. Provides human-readable explanations for every blocked action and a full audit trail for regulatory compliance.

Power BI Ontology Extractor: Unlocking 20M Hidden Ontologies
Built a tool that transforms Power BI data models into AI-ready ontologies — automatically extracting entities, relationships, and business rules from DAX measures. Generates OWL ontologies and MCP-compatible semantic contracts, enabling AI agents to reason over existing dashboard intelligence.

Self-Healing Multi-Agent System with MCP
Built an open-source multi-agent system that uses OWL ontologies and Model Context Protocol (MCP) to automatically adapt when database schemas change. Zero manual code fixes required on schema drift — the ontology layer detects changes and re-maps agent queries in real-time.

AI Agent Backend Benchmark: PostgreSQL vs Vector DB vs OWL Ontology
Conducted a rigorous three-way benchmark testing PostgreSQL, vector databases (Pinecone), and OWL ontology as backends for AI agent decision-making. Tested across loan approval domain with regulatory constraints. Conclusion: none of them won alone — a query router combining all three is the production answer.
