x-tracker
First cross-platform mobile app: student expense tracking. Built with Expo and React Native for an undergraduate final-year project. Never deployed to a store.
Mobile engineer
- React Native
- Expo
Problem
The FYP needed a mobile client on top of a Node.js REST API so students could log and review expenses on a phone.
What I built
- Shipped an Expo / React Native MVP with navigation, screens, and local data flows.
- Paired it with a Node.js REST API as the backend half of the final-year project.
Outcomes
- Used as the mobile MVP for a BSc Computer Science final-year project.
- Never published to the App Store or Play Store — an academic client, not a launched product.
Final-year mobile MVP
x-tracker is the first cross-platform mobile app I shipped for myself: a student expense tracker in Expo and React Native (2022).
It was the client half of my University of Nigeria Computer Science final-year project. The other half was a Node.js REST API. The mobile app was never submitted to a store and was never hosted as a consumer product.
I keep it here because it is the honest start of the mobile work that Companio will need later — navigation, screens, and a phone-shaped client — not because it is a launched fintech.
