I built EasyTech, a cross-platform mobile app that helps older adults learn and use digital technology. Its accessibility-focused interface includes large controls and adjustable text, and I published the app on Google Play.
For CompeTech, I developed the React Native mobile app for a school platform that digitizes student training-score tracking, evidence submission, and career-development workflows. The project was piloted at Nguyễn Chí Thanh High School, where feedback from 53 homeroom teachers reported high overall satisfaction and improved transparency and efficiency in student management.
I co-developed How To Love Viet Nam, a web and mobile learning platform for Vietnamese History and Local Education. I integrated AI learning tools, including a RAG knowledge chatbot and quiz generation; in a user evaluation, 88.23% of surveyed students reported a significant increase in learning interest.
