What I'm looking for

I'm looking to build scalable AI systems, distributed architectures, and cloud-native applications, with a focus on production-grade GenAI, RAG, AI agents, vector databases, and modern engineering practices.

I'm building production-grade GenAI systems at Genpact for Unilever and Walmart, including risk prioritization, reconciliation, and document intelligence workflows.

For Walmart, I developed AI-driven SAP Open Line validation, credit-note verification, pre-JE checks, and supplier communication. My GenAI automation for emails, attachments, and scanned documents reduced AP processing cycle time by 60–70% while improving real-time reconciliation and validation accuracy.

Previously at Shiprocket, I delivered responsive pricing experiences, Smart Assign, product update notifications, and improved order tracking. Smart Assign increased delivery success by up to 10% and reduced lost orders by 10%.

I'm also building NexusAi, a modular FastAPI, React, and Ollama platform with RAG, vector search, hybrid search, OCR ingestion, caching, reranking, grounded responses, and AI agents powered by LangChain, LangGraph, and MCP.
