Abhijeet Chauhan

Full-Stack Engineer Backend-leaning · AI & LLM systems

Full-stack engineer with four years of experience, most at home on the backend. I design APIs, services, and data models, deploy them on Google Cloud, and increasingly build with LLMs — agents, RAG, and workflow automation with Langchain. As BauAI's founding engineer I took an AI product from MVP to production and led a small team.

About

I'm a full-stack engineer who leans toward the backend. Most of my work lives on the server side — APIs, data models, microservices, and the infrastructure around them — and over four years I've taken these from first commit to production on Google Cloud.

A lot of that now revolves around LLMs: I build agents, RAG pipelines, and workflow automation with Langchain, then do the unglamorous work of making them dependable in production — clean data models, sensible CI/CD, and monitoring that catches issues early.
