Applied AI & engineering leadership

Chelsea leads a 53-person engineering organization and personally designs and builds applied-AI systems that public institutions can actually trust — grounded, privacy-safe, and constrained against hallucination.

• Independently designed and built a six-branch applied-AI suite on MyCareer.NJ — a grounded RAG career coach, semantic search, résumé/skill matching, predictive career intelligence, smart notifications, and content/accessibility automation — on AWS Bedrock inside the state VPC. A 50-state scan found no equivalent resident-facing grounded conversational AI.
• Built responsible-AI practices across the portfolio: prompt-injection defenses, automated red-team suites, hallucination evaluation, PII-safe logging, and circuit breakers. The career coach passed 6 pre-launch audits, 69 red-team tests, and 105 golden-answer validations.
• Leads with trust, psychological safety, and clear ownership — grew the org from 39 to 53 through company-wide change with unusually high retention, and promoted 9 engineers into senior and leadership roles.
• This very site is a demonstration: the assistant you can chat with here is a grounded RAG over Chelsea's real history, built the same way — it answers only from verified context and won't invent a fact.
