Created an interactive quiz-based learning app aimed at students preparing for exams. The goal was to make revision more engaging compared to static reading materials. The app featured timed quizzes, instant scoring, and topic-based question categories. One key challenge was designing a system that could randomize questions while maintaining balanced difficulty levels. I also focused on user engagement by adding progress tracking and simple performance analytics. During testing, users responded positively to the immediate feedback after each quiz, which encouraged repeated use. This project improved my ability to design educational tools that are both functional and engaging, while also reinforcing clean UI practices for better usability.

Developed a mobile app for a small event organizer who needed a better way to manage bookings and reduce manual communication with attendees. Before the app, most bookings were handled through WhatsApp, which led to missed messages and confusion. I built a system that allowed users to browse events, reserve slots, and receive confirmation instantly. The backend handled booking limits to prevent overbooking, which was a recurring issue before. One challenge was keeping the app responsive while syncing real-time booking data. I implemented efficient API calls and caching to maintain smooth performance. After deployment, the client reported a significant reduction in manual coordination and improved customer experience. The app streamlined their workflow and allowed them to scale event registrations more confidently.
