Babu.
AI engineer. I build the boring plumbing that makes intelligent systems actually useful — retrieval, evals, agents, and the small models that live close to the metal. This is where I keep my notes.

Shipped retrieval-augmented eval harness
Rewired the eval loop to run against a live vector index; latency down 41%, hallucination rate down to 3.2% on the internal benchmark.

A short piece on when a model is memorising versus reasoning, and the three signals I look for before I stop training.

Kavi — a small language model for Tamil poetry
First readable output. It rhymed. Badly. But it rhymed.
Things I've
built lately
A short catalogue. Some finished, most still moving. All documented in the log.
Set in DM Serif Display and Fira Sans. Printed digitally on off-white paper. No dark mode, no glass, no gradients. Just ink.
Letters, ideas, and consulting inquiries are welcome. I read everything, I answer most.
