WonderSync

Project Overview

Background

WonderSync is a comprehensive travel planning and management application designed to simplify group trip organization. As team lead and a developer, I directed a team of six developers to create an app that enables users to collaborate in real-time, making it easy to coordinate destinations, accommodations, and dining plans. Built with a focus on user experience and scalability, we championed the implementation of the MVVM architecture pattern and SOLID principles to ensure maintainable and extensible code. The project was completed over one semester, demonstrating successful leadership in both technical development and team management.

Key Features

Multi-Trip Planning: Users can manage multiple trips simultaneously, whether planning solo or with groups. Each trip generates a unique ID for easy collaboration.
Comprehensive Trip Management: Features include a logistics overview screen, destination planning with time calculations, dining reservation management, and accommodation booking coordination.
Travel Community Platform: Users can share their travel experiences, view others' trips, and engage through comments, creating a social aspect to travel planning.

Technical Implementation

Architecture

WonderSync implements the Model-View-ViewModel (MVVM) architecture to ensure clean separation of concerns. The ViewModel acts as a mediator between the View and Model, managing data logic and application state. Live data binding enables the View to observe ViewModel changes while focusing solely on UI presentation.

Challenges & Solutions

Real-Time Data Synchronization

Challenge: Ensuring data remained synchronized across multiple users in real-time.
Solution: Implemented Firebase's real-time database with proper data listeners and sync mechanisms.

Code Base Scalability

Challenge: Creating an expandable codebase while continuously adding new features.
Solution: Implemented SOLID principles, including Single Responsibility Principle for adapters and Dependency Inversion for ViewModels.

Sprint Management

Challenge: Meeting sprint deadlines while maintaining code quality.
Solution: Adopted daily scrums and utilized Jira for project management, improving team communication and task tracking.

Key Learnings

The project highlighted the importance of effective team communication through daily scrums and project management tools. We learned valuable lessons about architecture design, the benefits of SOLID principles in maintaining clean code, and the importance of proper sprint planning in meeting deadlines while maintaining code quality.
