BitcoinTAF – Crypto Wallet & E-Learning Platform

BitcoinTAF is a React Native crypto wallet and e-learning platform published on both the App Store and Google Play Store.

A standout piece of work is the custom HLS video player that streams Vimeo chunks with pinch-to-zoom powered by React Native Gesture Handler and YouTube-style quality control — working consistently across iOS and Android.

The video player was extracted into an open-source npm package: react-native-video-zoom, available for the React Native community.
