Jeweller · Forward Deployed Engineer at Gems Mart Jewellers

I'm a jeweller first — I run growth at Gems Mart Jewellers, a 25-year-old Delhi house. I also vibe-code, mostly at night, and I'm the forward deployed engineer for our own business: the estimators, the catalogue, the systems that used to be paper. Books, browser games and small tools are what the habit spills into.

FDE × Jewellery

Where most of my time goes. All of it built on real inventory — hundreds of CADs, karigar challans and supplier catalogues from a working Delhi jewellery house, rather than on a generic template.

AI Quote Estimator

Upload a photo of a piece, confirm two taps, get an honest price band in seconds. Built on 1,250+ real CAD and supplier-catalogue records rather than guesswork — with the pricing card editable by the jeweller, not hard-coded by me.

IIJS Exhibitor Intelligence

2,163 IIJS exhibitors scored before the show opens — who exports, who has a real web and Instagram presence, and which price tier they actually manufacture at. Built so I can walk the hall with a shortlist instead of a floor plan.

Commerce & Operations

Retail before I could code it, and data work since.

Writing

Four published books, a weekly paper on India's political economy, and a blog on gold and macro. Long-form is where I think properly — and the habit of testing an idea until it survives or dies honestly is the same one that keeps a price model trustworthy.

Blog

Geopolitics, finance, gold and macro — sourced, plain-English analysis connecting world events to markets.

Games & Tools

Around twenty browser games and a handful of free tools — a football club to run, a nation to govern, a planet to fly. Made for the pleasure of making them; they're also where the shipping habit came from.
