I am a Computer Science student at the University of Luxembourg, with hands-on experience in mobile app development and web engineering.
I have two published apps on the App Store: a privacy-focused expense tracker with on-device ML categorization, and a birthday reminder app with local notifications and calendar management. Both are built with React Native, Expo, and TypeScript using offline-first architecture.
I also built the production website for INIZIO Wellness & Beauty, a Luxembourg salon: four languages, 88 indexable pages, and a complete path from discovering a service to booking a visit.
