About

I build software that millions of people use every day — and I care deeply about the milliseconds that separate a great product from a great experience. Over 8+ years across Dream11, Rebel Foods, and Cimpress, I've grown from writing my first React component to leading frontend architecture for India's largest fantasy sports platform, serving 200M+ registered users. At Dream11, I've owned everything from performance optimisation and CI/CD pipeline automation to driving 0→1 features shipped to tens of millions of active users. My core stack: React Native · React.js · JavaScript (ES6+) · TypeScript · Node.js · AWS · Firebase. I'm obsessed with app performance, clean component architecture, and making deployment faster and more reliable for the teams around me. I've operated in hyper-growth environments where a bad deploy means headlines — and that pressure has made me a sharper, more deliberate engineer. If you're building something ambitious in mobile or web, let's talk: udiwal789@gmail.com
