tPago

About the project

tPago is a mobile payment platform for transfers, service payments, phone top-ups, and checking financial products from one place.

I worked on tPago during my first time at GBH, early in my career as a mobile software engineer. It was one of the projects where I started building the practical foundation I still use in React Native projects today.

My part

The Android app was native. I was its main developer and was in charge of maintaining it, fixing the problems that appeared, and keeping it moving as the product changed.

Later, I was assigned to create the iOS equivalent from the ground up using React Native. It was a very different responsibility from maintaining an existing application. I had to understand what the Android product already did, decide how that translated to iOS, and build a new cross-platform foundation without losing the behavior people already expected from tPago.

Working on both sides gave me an early understanding of something that has followed me through my career: cross-platform development still requires respecting each platform. React Native can share a lot, but the product still has to feel and behave correctly on the device where it is running.

Looking back

This project belongs to an important part of my career. I was learning how an existing native product is maintained, how a new app is started, how a mobile team coordinates changes, and how small implementation details become much more important once an app is in the hands of actual users.
