About

Staff-level Full Stack Engineer with 11.8 years building high-scale web platforms, microservices, data pipelines, and production AI systems — end-to-end across React/TypeScript, Java Spring Boot, Node.js, and Apache Airflow. At Walmart Global Tech, I architected a production RAG pipeline (pgvector + LangChain) that cut analyst report turnaround by 70% and eliminated manual SQL work for business teams. I led the DOOH in-store advertising network expansion to 7 channels — $228K+ campaign budgets, 1.3M+ ad plays/month — and built the Java Spring Boot microservices behind it, cutting p99 validation latency 40%. I own the full-stack campaign dashboard (React/TypeScript, Java Spring Boot + Node.js/Express, PostgreSQL + BigQuery) and the Airflow pipelines that feed it. Before Walmart, at Nagarro, I scaled the Spark Driver platform from 6,000 to 150,000+ active drivers (25x) — Java Spring Boot APIs, a React/Next.js component library at 100% test coverage, and AWS infrastructure that held under the load. That work earned me a direct FTE offer from Walmart. I operate across the stack with a systems-design mindset, measurable impact at every layer, and a habit of mentoring engineers into their next level (2 mentees promoted; one intern's project earned them a full-time offer). Walmart restructured in 2026 and my role was impacted — so I'm now looking for Staff Full Stack or Staff Platform Engineering roles where I can own systems end-to-end: API design, data infrastructure, frontend, and AI/LLM systems. Open to Bengaluru, remote, and relocation. If you're hiring or know a team that's a fit — React/TypeScript, Java, Node.js, distributed systems, RAG/LLM — I'd welcome a message.
