Full Stack Developer at NVIDIA building AI knowledge assistants and agentic workflows for enterprise applications.

At NVIDIA, I develop enterprise web applications with Java, Spring Boot, React, and PostgreSQL. I also built an AI-powered knowledge assistant using Spring AI, LangChain4j, RAG, and vector search, reducing document search time by 55%.

I’ve built secure REST APIs and responsive React components, and developed agentic workflows for document retrieval, API orchestration, and response generation. My work has included integrating Kafka and deploying containerized applications on AWS.

At PayPal, I developed payment and merchant management applications and integrated generative AI capabilities into internal developer tools. I also developed agentic services for payment verification, merchant onboarding, and fraud investigation workflows.
