Experience

DeinDeal eCommerce App

A native Android app for online shopping and food delivery. I took ownership of the project with little to no documentation after the previous developer had left. I have since refactored the majority of the codebase while still adding new features and bug fixes.

UMFa Quiz App

A native Android app designed to help future students prepare for the University of Medicine and Pharmacy admission exam.

The app consisted of both local quizzes (training and scored) and a real-time "battle" type quiz where you competed against other users. I was the sole developer for Android and implemented features such as custom views for user statistics, in-app subscriptions, and Google AdMob integration.

Libon VoIP App

Contributed to the development of the Libon Android app. It's a VoIP and messaging app that allows users to call mobile and landline phone numbers in more than 150 destinations around the world at very low rates.
