Fragments 2019

Zerodha is India’s biggest retail stock broker, known more as a fintech company than a broking company. Our flagship web and mobile trading apps, Kite, generate 3+ million orders a day, the largest in the industry, contributing to over 10% of all retail volumes across Indian stock exchanges.

Kite 3.0 mobile, the third major iteration of the app, is written from scratch in Flutter. The first two generations were native and React Native respectively. Just two developers learnt, became productive in Flutter, and took the app to market in a handful of months. In this talk, I will share our experience using Flutter, the challenges we faced, and in the end, the amazing productivity boost, app performance, and the additional UI/UX benefits we achieved.
