A concrete example of why this matters: at Optum, I redesigned an enterprise integration mapping process around a governed taxonomy + semantic model and cut redundant mapping work by roughly 80%. That is the kind of leverage taxonomy, knowledge graph, and policy-as-code governance can create. What I bring to teams building AI in regulated, data-heavy environments: - Taxonomy & ontology design that makes search, retrieval, and AI outputs accurate and explainable - Knowledge graph + semantic data architecture for RAG, data catalogs, and AI systems - Active metadata governance using policy-as-code and SHACL/OWL constraints so data quality rules are enforced automatically, not just documented - Regulated-sector experience across healthcare, finance, and federal-adjacent projects Open to senior Data Architect / Knowledge Graph / AI Architecture roles ($200K+). Remote or hybrid preferred. DMs open — happy to share the repo or jump on a quick call. #OpenToWork #RecruitersWelcome #DataArchitecture #KnowledgeGraph #AI #SemanticWeb #Governance #Hiring

If I were rebooting The Last Starfighter, I wouldn’t make another movie—I’d make a long-running streaming series. Season 1 (10 episodes): 1️⃣ Alex breaks the high score and is recruited. 2️⃣ Star League Academy begins. 3️⃣ Gunstar flight training. 4️⃣ A spy is discovered inside the Star League. 5️⃣ Maggie learns the truth. 6️⃣ A lost Star League fleet is found. 7️⃣ First mission into Ko-Dan space. 8️⃣ Betrayal changes the war. 9️⃣ Alex leads his first battle. 🔟 Victory…until an even greater threat emerges beyond known space. The original film becomes the beginning—not the entire story. Build the Star League into a universe that can run for years. I’d subscribe on day one. #TheLastStarfighter #SciFi #Streaming #SpaceOpera #Television #ScienceFiction
