Background
AI infrastructure engineer and instructor. Founder of Raptor Cybersecurity LLC. Author of two patent-pending provenance systems for LLM output validation (RAPTOR-CR-2026-001, RAPTOR-CR-2026-002).
The curriculum at AI Knowledge Hub is grounded in production systems shipped in regulated industries — defense industrial base cybersecurity, clinical documentation, and legal evidence handling — where retrieval-augmented generation has to be provably correct, not merely impressive.
Teaches
- Vector database engineering
- Hybrid retrieval (dense + sparse)
- Knowledge graph modeling
- GraphRAG and multi-hop reasoning
- Embedding fine-tuning
- Production evaluation systems
- LLM provenance and validation
- Self-hosted LLM deployment
