This podcast details the mobile engineering practices at Notion, a productivity app with over 100 million users. The discussion covers the team's evolution from a WebView-based app to a primarily native architecture, highlighting their incremental approach focusing first on performance improvements to the Home tab. The team, surprisingly small at 11 engineers, emphasizes weekly performance reviews and uses a unique RFC process driven by engineers, facilitated by Notion itself. Listeners gain insights into the challenges and strategies of building and maintaining a large-scale mobile application, including the importance of fast build times and the strategic use of feature flags.
