At S&P Global, I design Java enterprise applications and a GenAI platform on GCP using Vertex AI, Gemini, and open-source LLMs. I build RAG solutions with LangChain and LangGraph, including document processing, vector search, and context-aware response generation.
I also design agentic workflows that connect Java microservices to LLM agents through secure tools, and define guardrails such as prompt-injection defense and PII masking. I lead and mentor a team of six engineers while staying involved in architecture, coding, reviews, and delivery.
On the Enterprise RAG-Based Knowledge Assistant, I developed document retrieval and a React chatbot for service documentation and run books, deployed on GCP. Earlier, at OPDM/DMT and SNAPHISH, I developed SOAP and REST microservices, asynchronous integrations, and a shopping cart module.
