From PHP Developer to React Native: My Journey into Mobile

For over a decade, I was primarily a PHP developer. Laravel was my bread and butter, MySQL my comfort zone. When I got the opportunity to build a React Native app for Interamerican, one of Greece's largest insurance companies, I was both excited and terrified.

The learning curve was steeper than I expected, but not in the way I anticipated. JavaScript itself was familiar from years of frontend work. The real challenges were understanding the mobile paradigm: navigation stacks, native modules, platform-specific behavior, and the entirely different debugging workflow.

Push notifications were my first major hurdle. Getting Firebase Cloud Messaging working consistently on both iOS and Android, handling background notifications, deep linking from notification taps — it all required understanding platform-specific quirks that no amount of web development prepares you for.

Payment integration was another significant challenge. Implementing secure in-app payment flows required understanding App Store and Google Play guidelines, PCI compliance considerations, and the differences between how iOS and Android handle payment callbacks.

What made the transition smoother was my backend experience. Understanding API design, authentication flows, and data modeling gave me a huge advantage. I could design the mobile app's data layer knowing exactly how the backend would serve it.

My advice for backend developers considering mobile: do not try to learn everything at once. Start with a simple app, get comfortable with navigation and state management, then tackle native modules and platform-specific features. The React ecosystem knowledge transfers well, but mobile has its own world of concerns.
