Project Overview

Built an iOS marketplace app in 2 weeks for Cornell's AppDev Hack Challenge that connects pet owners with student sitters on campus.

The app features dual interfaces: pet owners post sitting requests with pet details, dates, and location, while sitters browse and filter opportunities by pet type, activity level, and campus area. I led frontend development in Swift, implementing role-based authentication, dynamic filtering, and the complete user interface for both owner and sitter experiences.

Technical Implementation

1. iOS development: Built native Swift app with role-based authentication (Pet Owner/Sitter) and custom NetworkManager using URLSession for API communication
2. Dynamic filtering: Implemented real-time filtering system allowing sitters to search by pet type, activeness level, and campus neighborhood location
3. Pet listing management: Built functionality for creating, viewing, and deleting pet postings with detailed information cards, image handling, and empty state designs
4. Backend integration: Integrated with Python backend featuring RESTful API with user authentication, pet posting models, and database operations
