Wait4Me

1. Cross-Platform Flutter Mobile App

• Developed a high-performance Flutter and Dart mobile application for iOS and Android, supporting both client and assistant roles within a single, cohesive interface ecosystem.
• Implemented clean architecture principles with separate Data, Domain, and View layers, using GetX for state management, the repository pattern for data abstraction, and GetIt for dependency injection across multiple API environments.
• Built role-based navigation and dashboard experiences allowing users to seamlessly switch between acting as a client posting tasks and an assistant browsing and bidding on assignments.

2. Assignment Management System

• Developed a comprehensive assignment management system covering task creation, editing, status tracking, bidding, search, and multi-parameter filtering for both clients managing their posted tasks and assistants browsing available opportunities.
• Built intuitive task creation flows with pre-filled assignment data support for the paid search onboarding flow, reducing friction for new users entering the platform through paid acquisition channels.
• Implemented real-time assignment status tracking providing clients and assistants with clear, up-to-date visibility into task progress from bid acceptance through to completion.

3. Real-Time Chat and Notifications

• Implemented real-time bidirectional chat using Socket.IO, providing immediate and reliable communication between clients and assistants with online status indicators and inbox management.

4. Payment Integration and Transaction Management

• Integrated PayPal payment processing with a secure escrow-style payment release workflow, ensuring assistants received payment only upon task completion and client confirmation.
• Built a full transaction history system allowing users to review past payments, released funds, tips received, and promo code redemptions from within the app.
• Implemented tip functionality and promo code support to incentivize quality service delivery and drive user acquisition and retention.

5. Location Services and Google Maps Integration

• Integrated Google Maps for location-based assistant search, enabling clients to discover and hire nearby assistants based on real-time proximity and availability.
• Built location selection tools and multi-location task support for assignments requiring assistance across more than one location or involving movement-based errands.
• Optimized location-based matching to surface the most relevant and available nearby assistants quickly and accurately across the platform.

6. Authentication and User Management

• Implemented multi-method authentication including social login via Apple and Google, OTP-based verification, and full profile management with user preferences and account deletion support.
• Built user management tools including block and report functionality to protect platform integrity and give users control over their interaction environment.
• Integrated AppsFlyer attribution tracking to accurately measure paid versus organic install performance and optimize user acquisition strategies.

7. Advanced Platform Features

• Implemented a Firebase Remote Config-powered version update system supporting both force and optional app updates, ensuring all users operated on supported platform versions.
• Developed iOS quick actions for fast access to key platform features directly from the home screen, improving power user efficiency and engagement.
