At Visa, I lead the production Data Works Agentic AI platform: a LangGraph multi-agent system with RAG retrieval, natural-language querying, and guardrails that cuts analyst time-to-insight from hours to minutes.
I've built the knowledge ingestion pipeline across 15+ enterprise data sources, benchmarked and selected PgVector for sub-second retrieval, and used LangSmith traces across 10K+ weekly runs to improve retrieval precision by 25%. I also own architecture, OpenAPI contracts, and GenAI API standards across four engineering pods while mentoring six engineers.
Previously, I owned Quest, Visa Data Platform's 50+ node OpenSearch cluster serving 20+ teams, leading a zero-downtime migration from Elasticsearch ELK and reducing p95 query latency by 40%.
My platform work spans 900+ node Kubernetes clusters, GitOps, CI/CD, observability, developer tooling, and secure self-service delivery. I've shipped Pipeweed and Vault-as-a-Service, helped 150+ repositories migrate to GitHub Actions, contributed to CPython and Pytest, and co-organized the BangPypers Python community.
