💡 What I Built

A full-featured collaborative note-taking platform built with React and Firebase, designed to help users organize knowledge, manage projects, and structure content hierarchically. This application demonstrates advanced concepts in state management, recursive data structures, and real-time synchronization.

Core Features Implemented

  • Google OAuth Integration — Seamless authentication using Firebase Google Sign-In providing secure, password-less access with automatic user profile creation

  • Multi-Workspace Architecture — Built workspace management system allowing users to create multiple isolated workspaces, each with its own set of pages and content organization

  • Hierarchical Page System — Implemented unlimited nested page structure with parent-child relationships, enabling users to organize content in tree-like hierarchies of any depth

  • Rich Page Customization — Developed page personalization features including custom cover images, emoji icons, and page titles for visual organization and quick identification

  • Tree Navigation Sidebar — Created collapsible sidebar displaying full page hierarchy with expand/collapse functionality, drag-and-drop reordering, and visual nesting indicators

  • Breadcrumb Navigation — Implemented dynamic breadcrumb trail showing page hierarchy from workspace root to current page, enabling quick navigation up the hierarchy

  • Rich Content Editor — Built content creation system supporting multiple content types including H1/H2 headings, paragraphs, and other text elements with proper formatting

  • Real-Time Data Persistence — Integrated Firebase Firestore for automatic content saving with real-time synchronization ensuring no data loss and instant updates

  • Workspace Dashboard — Created Trello-inspired workspace overview with card-based layout for easy workspace management and quick access

  • Individual Workspace Mode — Implemented single-player functionality allowing focused work without collaboration distractions

  • Responsive Interface — Designed mobile-friendly layout adapting to different screen sizes while maintaining full functionality

  • Page Management Operations — Built complete CRUD operations for pages including create, read, update, delete with proper authorization checks

🛠 Tech Stack

Frontend Framework: React 18 with Vite build tool
State Management: React Context API and hooks
Database: Firebase Firestore (NoSQL)
Authentication: Firebase Authentication with Google OAuth
Hosting: Netlify with continuous deployment
Routing: React Router for SPA navigation
Styling: Modern CSS with responsive design
Data Structure: Recursive tree structures for nested pages
Real-Time Sync: Firestore real-time listeners

🚀 Why This Project Matters

This project demonstrates my ability to:

  • Build complex hierarchical data structures with unlimited nesting depth
  • Implement recursive algorithms for tree traversal and rendering
  • Design intuitive information architecture for knowledge management
  • Handle real-time data synchronization across multiple clients
  • Create performant React applications with optimal re-rendering strategies
  • Integrate Firebase services (Auth, Firestore) in production applications
  • Build collaborative platforms with proper data isolation
  • Write maintainable component hierarchies for complex UIs
  • Implement OAuth authentication flows securely

🏗 Architecture Highlights

  • Recursive Component Architecture — Built reusable page tree components that render themselves recursively to display unlimited nesting levels

  • Firebase Data Modeling — Designed Firestore collections for workspaces, pages, and content with proper relationships using document references and subcollections

  • Context-Based State — Implemented React Context for global state management of current workspace, user session, and navigation state

  • Optimistic Updates — Applied optimistic UI updates for instant feedback while Firebase operations complete in background

  • Tree Data Structure — Utilized parent-child relationships with efficient algorithms for tree traversal, insertion, and rendering

  • Route Protection — Protected routes requiring authentication with route guards redirecting unauthenticated users

  • Component Composition — Structured UI using composable components for workspace cards, page items, content blocks, and navigation elements

  • Firebase Listeners — Leveraged Firestore real-time listeners for live updates when pages or content changes

  • Lazy Loading — Implemented code splitting and lazy loading for optimal bundle size and faster initial load

📊 Technical Achievements

  • Unlimited Nested Pages with recursive rendering
  • Google OAuth integration with Firebase
  • Real-Time Synchronization across all users
  • Tree Navigation with expand/collapse functionality
  • Breadcrumb Trail showing page hierarchy
  • Cover Images & Icons for page customization
  • Workspace Management with Trello-style UI
  • Rich Text Content with multiple heading levels
  • Data Persistence with Firestore
  • Responsive Design across devices
  • Production Deployed on Netlify

🎯 Key Technical Challenges Solved

1. Infinite Nested Page Hierarchy

Designed a recursive component system that renders page trees of unlimited depth while maintaining performance and proper state management at each level.

2. Real-Time Tree Updates

Implemented efficient Firestore listeners that update the page tree in real-time when pages are added, moved, or deleted without requiring full tree refresh.

3. Breadcrumb Generation

Built an algorithm to traverse from child page up to root workspace, generating accurate breadcrumb trails for navigation context.

4. Workspace Isolation

Ensured proper data isolation between workspaces while sharing user authentication, requiring careful Firestore query design and security rules.

5. Complex State Management

Managed application state across nested components including current workspace, selected page, editor state, and navigation state using Context API effectively.

🌟 Application Capabilities

  • Knowledge Organization — Structure information in hierarchical page trees
  • Multi-Workspace Support — Separate different projects or areas
  • Visual Customization — Add covers and icons to pages
  • Quick Navigation — Sidebar tree and breadcrumbs for easy browsing
  • Content Creation — Write and format notes with headings and paragraphs
  • Auto-Save — Automatic content persistence with Firestore
  • Secure Access — Google authentication for user accounts
  • Real-Time Sync — See changes instantly across devices
  • Workspace Overview — Dashboard with all workspaces at a glance
  • Focus Mode — Individual workspace mode for distraction-free work

💡 Use Cases

  • Personal Knowledge Base — Organize personal notes and learnings
  • Project Documentation — Structure project docs hierarchically
  • Meeting Notes — Quick note-taking with organized structure
  • Content Planning — Plan and outline content with nested pages
  • Study Notes — Organize academic material by subject and topic
