In this episode of On Rails, Nadia Odunayo, founder and solo developer of The StoryGraph, joins us to share what it really takes to build and maintain a Rails application used by over four million readers across web and mobile.

We discuss lessons from launching a PWA, shifting to Turbo Native for cross-platform support, and navigating challenges like in-app purchases and data syncing between systems. Nadia also talks about the bold decision to move from Heroku to YugabyteDB to support growing workloads, and why she decided against hiring a team to manage it.

We also explore what it means to remain a solo developer by choice, the value of the Rails community, and why Ruby on Rails continues to be the framework that powers her entire business.
