Key Architectural Features
JWT and Google OAuth2 authentication on the web application.
Kanban-style drag-and-drop task boards for intuitive workflow organization.
Real-time WebSocket notifications for immediate task assignment and state-change updates.
Project and milestone tracking integrated with comprehensive calendar views.
Flutter mobile app with secure encrypted JWT token storage, auto-login, and Provider-based light/dark theming.
Mobile-specific derived task views: overdue, upcoming, and today's tasks, plus calendar-based task navigation.
Advanced status and priority filtering on the mobile client.
Challenges & Engineering Solutions
System Failure Mode Under Peak Load
Designing a shared REST API that satisfies both the rich React web app interaction patterns and the mobile-optimized Flutter client simultaneously, while maintaining consistent real-time state across all clients.
Architectural Strategy & Resolution
Implemented a robust WebSocket-based notification architecture with optimistic UI updates in React, and an independently architected Flutter mobile client consuming the same FastAPI backend with Provider state management and encrypted local storage.
Frontend built with React and TypeScript; Flutter mobile app independently designed with Provider state management and secure local storage. Both clients communicate with a shared FastAPI backend over REST and WebSockets, with MongoDB for flexible document storage.
Performance & Benchmarks
