Top Skills
Featured Projects
Building Agentic AI Applications with LLMs
NVIDIA Certificate
I built a deep research agent — ask it a question, and it autonomously decomposes the task, executes multi-step web search plans, and synthesizes structured, source-grounded answers. Powered by NVIDIA NIMs and LangGraph for scalable, serverless agent orchestration.
Featured: Real-time ranking pipeline handling 120M recommendations/day with 30% infra savings via quantization + on-device caches.
