Hey, I'm Sonu 👋

Backend engineer with a little too good knowledge of llms and the systems that could be built around them. Started with Javascipt + node js, now I build RAG pipelines and agentic systems — with enough LLM internals under the hood to know why things break, not just that they did.

I Always to learn things from first principle first.

What I do: RAG pipelines, agentic systems, backend that doesn't fall over — and enough handle on transformer internals to reason about the model, not just call its API.
