📌 Project Overview
CatchPlan is an Android app that provides a comprehensive list of events nationwide along with AI-based personalized recommendations and calendar management features.
Event data is automatically collected through web crawling from platforms like YES24, ensuring up-to-date information for users.
Users can receive tailored event recommendations and save their favorite events to their personal calendar.

🎯 Motivation & Key Objectives
- Solve accessibility issues caused by scattered event data
- Provide personalized event recommendations
- Promote lesser-known events and expand visibility

📖 Key Features
- AI-powered recommendation system using MBTI-based similarity matching
- Chatbot for handling user queries related to the app
- Scrap and calendar features for managing favorite events in one view

🙋‍♂️ My Role & Reflections
- As a backend developer, I handled DB design, JWT token generation & validation, overall API design, and HTTPS setup on EC2.
- It was my first time doing server-side development and participating in a team project, which I expected to be very challenging. Thankfully, thanks to the team's active participation and help from senior developers, we successfully completed and launched the app.
