I'm Rajeev Ranjan, a full-stack & AI engineer based in Surat, India. I'm the Tech Lead at Originn and a Data Science student at IIT Madras.

I like the hard, end-to-end parts of building software: designing a schema, shaping an API, wiring a real-time pipeline, and then making the whole thing feel effortless on screen. Lately a lot of that work lives where products meet AI — voice agents, RAG systems, and LLM-powered workflows.

I ship constantly. Beyond the projects here there are dozens of smaller experiments — a PC-controlling AI agent, a voice-synthesis studio, computer-vision tools — collected in the Lab.
