From prototype to production AI: RAG pipelines, multi-agent chatbots, enterprise platforms | SWE II @ McKinsey | React · Python · LangChain · AWS · Kubernetes

About

Most AI projects die between the demo and production. My job is getting them across that gap. At McKinsey, I build enterprise platforms end-to-end — React/Next.js frontends, NestJS and Python backends on AWS and Kubernetes — and the AI systems inside them: RAG pipelines with vector search, multi-agent chatbots using LangChain, and LLM workflows that run in production for thousands of users, not in notebooks. Before McKinsey: 4 years across Divami Design Labs, IMG Global, and TCS, shipping e-commerce platforms, education products, and enterprise portals. Currently pursuing an M.Tech in AI & Machine Learning at BITS Pilani — deep neural networks, reinforcement learning, NLP, and ML systems optimization. Recent work: a multi-agent chatbot that lifted user engagement 50%; platform load-time improvements of 40% via SSR and code optimization; CI/CD pipelines on Kubernetes that cut deployment errors by a third. Stack: React, Next.js, TypeScript, Node.js, NestJS, Python, PostgreSQL, AWS, Kubernetes, Docker, LangChain, RAG, LLMs, multi-agent systems, microservices, system design. If you're hiring senior full-stack or AI/ML engineers who can own a system from architecture to deployment — my inbox is open, and I respond fast: yadavpraveen1023@gmail.com
