Duong Nguyen Xuan

I’m a goal-driven software engineering developer focused on creating creative, unconventional products while exploring the full breadth of modern technology. I’m passionate about leveraging emerging tools to redefine how software is built, integrated, and experienced.

In my Mobile App Development Internship at eUp Group (Ezami), I developed a cross-platform React Native application for online courses and mock tests, delivering a consistent UI/UX across iOS and Android. I implemented core user flows—authentication, quizzes, courses, wishlist, and profile management—and supported sprint execution through testing and release preparation to help stabilize the app toward production readiness.

On my projects, I’ve been building end-to-end products that blend AI and real-world usability. PractiSense, an AI-powered learning and revision app, uses Gemini API to evaluate user-submitted answers, highlight issues, and provide actionable improvement tips, including AI-enabled question generation from existing data.

I also build full-stack and IoT-enabled experiences. I created Yami, a food delivery platform that connects customers, merchants, couriers, and support agents with order flows, real-time updates, QR payments, and menu suggestions, plus modular role-based access control. For hardware + app integration, I developed PomoMentor with Arduino and device detection, then connected it to mobile via ESP32 for remote control and productivity tracking.
