Craft Trading

app store

A cross-platform paper-trading simulator for the Indian stock market, live on the App Store. Real-time trading, portfolio management, and social sharing.

Live on the App Store

the problem

Existing paper-trading apps are either too complex for beginners or lack the feedback loop that makes practice stick.

what i built

Built a mobile-first experience combining intuitive trading with social accountability, real-time price sync over WebSockets, and performance visualisation.

why it's interesting

Proof I take things all the way to shipped. Real-time sync, Redis pub/sub, App Store review, and production users - the unglamorous half of engineering that decides whether a system is real.

built with

react native, expo, typescript, node.js, postgresql, redis, websockets, aws
