Sam Meyer's Head of AI portfolio: production RAG, governance, and agents.

The lead is the regulated AI work shipped at scale. Public repos back the hands-on claim.

Top proof

Enterprise GenAI portfolio (Bristol Myers Squibb)

Owned the enterprise generative-AI portfolio for a global Medical Affairs organization: a production RAG platform serving ~2,000 users across 50+ markets, an ~$8M annual GenAI and digital portfolio, governed under GxP and 21 CFR Part 11.

Production RAG system (hands-on)

Built and governed retrieval-grounded generation for regulated Medical Affairs workflows: hybrid retrieval, ranking strategies, evaluation rubrics, grounding and drift review, human-in-the-loop gates, LLM-as-a-judge, and audit traces. FastAPI / retrieval / AWS. Confirmed hands-on by a technical peer.

$74B M&A technology integration

Led Celgene Medical Affairs IT workstreams across 20+ platforms, 1,500+ users, and 50+ markets in 18 months. Delivered $7M in operating efficiency and $4.3M in annual cost avoidance.

Featured builds

AI Governance Control Plane

Go gateway in front of every MCP tool call, applying Cedar policy, identity binding, Slack approval gates, and audit sinks. Aligned to the OWASP LLM Top 10 as the prompt-injection and excessive-agency boundary.

Retrieval Evaluation Stack

RAG evaluation pattern measuring recall and ranking with NDCG, MRR, MAP, and P@k, plus paired bootstrap, Holm correction, Cliff's delta, and TOST equivalence. Grounding checks flag unsupported answers.

Open Brain

Semantic memory MCP server (spec 2025-11-25) with hybrid FTS5 keyword plus vector recall, running locally with no per-call token spend.

Agentic Dev Pipeline

Label-driven GitHub Actions flow where issues become plans, human-approved work, tests, and pull requests, with scope controls and explicit verification paths.

CallToProposal

Live product that turns discovery-call transcripts into client-ready proposals, SOWs, estimates, and HIPAA BAAs, with deterministic WBS estimation, PHI gates, and audit logs.

SceneLock

Live product surface for cost-aware AI video generation: itemized cost preview, budget caps, BYO provider keys, encrypted key vault, Temporal workflow, and production health checks.
