Over the last 6 years we at Klarna have been building several React and React Native apps from the same codebase. We’ve scaled to 500 contributors per month, 85 million app downloads, and 30 million monthly active users. It’s been a wild ride and in this talk you will hear all about the challenges we faced, mistakes we made, and most importantly what we’ve learned from them. 🗣 Speaker Bio Mike Duminy is a Principal Engineer and Architect at Klarna, where he works on scaling React Native. He has been building React Native apps for the last eight years. He spent several years in startups, fostering pragmatism while resisting the lure of perfectionism. Ever curious, he enjoys exploring new ideas, solving problems, gaming, tackling coding challenges, engaging in philosophical discussions about language, and reading sci-fi/fantasy.
