Senior GenAI Solutions Architect at NVIDIA. I build AI systems that work in production — RAG pipelines, knowledge graphs, LLM agents — and occasionally ship products that put those systems in people's hands.

Background
I started in hardware — an Electrical Engineering dual degree from IIT Madras, where I also co-founded Dynamove, an ADAS startup building intelligent dashcams for Indian trucking fleets. That went through Axilor Ventures and reached the Top 50 at IIGP 2018, which was enough to convince me that building real products on top of cutting-edge research was worth doing full-time.
From there I went to CMU's Robotics Institute for a master's in Robotic Systems Development, then joined NVIDIA where I spent several years on autonomous vehicle software — working on the NVIDIA Xavier SoC and the DRIVE AV platform with Mercedes-Benz. In 2024 I made the shift to generative AI, which is where most of the interesting unsolved problems now live.
My current work at NVIDIA sits at the boundary between research and production: translating LLM capabilities into things that actually run reliably at scale. That means RAG systems, knowledge graph pipelines, NIM microservices, and agentic architectures. I published HybridRAG — a paper on combining vector retrieval with graph-structured context — with colleagues from NVIDIA and Citadel at ACM ICAIF 2024. I also maintain an active technical blog and have spoken at Graph the Planet 2025 on GPU-accelerated GraphRAG.
Timeline of You started as a hackathon project at the LlamaIndex Agentic RAG-a-thon 2 in October 2024 — we won 1st place Grand Prize out of 454 participants. The original prototype used agentic RAG to ingest career evidence from multiple sources, build a knowledge graph, and generate EB-1A petition documents. It's been a product since. Separately, I won 1st place at the Stanford LLM x Law Hackathon in April 2025 with JurisLink, a tool that maps conflicts of interest across legal databases and corporate structures for international arbitration. Same underlying instinct: AI is most useful when it's doing structured reasoning over messy real-world data, not just generating text.
Projects
1st place Grand Prize at the LlamaIndex Agentic RAG-a-thon 2 (October 2024, Palo Alto — 454 participants, $6,000 prize + OpenAI office hours). Agentic RAG system that ingests career data from resumes, LinkedIn, patents, and publications; builds a knowledge graph; and generates tailored EB-1A petition letters, recommendation letters, and citation maps. Now a full product.
Published research combining GraphRAG and VectorRAG for information extraction over financial documents. Outperforms either technique alone on Q&A benchmarks. Co-authored with colleagues at NVIDIA and BlackRock.
1st place, Stanford LLM x Law Hackathon #5 (April 2025, 80+ teams). Knowledge-graph engine that maps connections across legal databases, corporate structures, and public records to identify conflicts of interest in international arbitration.
Presented at Graph the Planet 2025 on building production RAG pipelines with LLM-driven knowledge graphs on NVIDIA infrastructure. NVIDIA Technical Blog author covering LLM knowledge graph techniques.
Co-founded at IIT Madras (2017). Intelligent dashcams and ADAS for Indian trucking fleets. Axilor Ventures W18 cohort. Top 50 in IIGP 2018 Open Challenge — only student-run early-stage startup in the cohort. 2nd place out of 2,000+ global teams in a competitive challenge.
AI-powered creative studio project. Details coming soon.
Autonomous AI agent running on Raspberry Pi with a phone number, email, and brokerage access — capable of trading options and publishing blog posts independently. Documented on personal blog (Feb 2026).

All guides on Timeline of You are written by me. The EB-1A content draws on direct experience building LLM-powered evidence analysis, studying USCIS adjudication patterns, and talking to researchers and engineers who have gone through the petition process.
