About

Kashmir

I’m a full-stack engineer from Kashmir who likes owning the whole thing: the API, the integrations, the deployment, and the interface people actually touch.

Most recently I was lead engineer and architect at a small studio, where I built a stays marketplace for a remote valley, a white-label commerce platform that AI agents can operate over MCP, and conversational booking agents on WhatsApp. Before that: distributed data pipelines on AWS Lambda, and real-time transcription and contact-centre integrations at Kore.ai.

I studied Electrical Engineering at IIT Hyderabad. On the side I write open-source agent skills, scrape things, and make generative art.

A GEO audit is a checklist, not a ranking model

What an audit of a young marketing site found, and why fixing every point on the checklist still wouldn't have moved it off page six.

A shop on a key-value store: index arrays, immutable Stripe prices and what you give up

Modelling products and collections in Workers KV, syncing them to Stripe without breaking history, and the reliability limits of a store with no queries.

Demo mode as signed config, not a fork

Ephemeral public demo stores that can't send email, take payments or be crawled, driven by one flag in the same signed document as everything else.
