Staff-level Full Stack Engineer with 11+ years designing and operating high-scale web platforms, microservices, data pipelines, and production AI systems. I operate end-to-end — React / TypeScript frontends through Java Spring Boot microservices to Airflow pipelines — with a systems-design mindset and measurable impact at every layer.
At Walmart Global Tech, I architected a production RAG pipeline that embedded 12-month ad campaign performance history into pgvector, orchestrated retrieval via LangChain, and exposed a natural-language analytics interface — eliminating manual SQL dependency for business teams.
I led DOOH in-store ad network expansion to 7 channels supporting $228K+ campaign budgets, and scaled Walmart's Spark Driver gig platform from 6,000 to 150,000+ active drivers while earning a direct FTE offer from Walmart Global Tech.
