11+
A running collection of the projects I've made and worked on — ranging widely, made carefully.
I'm Sanjeev — a data and pricing analyst by trade, and a maker by instinct. By day I turn large, messy datasets into decisions across financial services: pricing, portfolio performance, and the story the numbers are trying to tell. The rest of the time I build things — products, tools, and experiments that usually begin as a question I wanted answered. What ties it together isn't the subject but the approach: get into the detail, then leave it clearer and more useful than I found it — whether that's a pricing model or a football-stats rabbit hole at midnight.
A wide range of topics — filter to explore what interests you.
