💡 What I Built

A fully functional social community platform inspired by Reddit, built from scratch with Angular 15 and Firebase. This application handles complex user interactions, real-time data synchronization, and multi-level content hierarchies, demonstrating proficiency in building production-ready web applications.

Core Features Implemented

  • Complete Authentication System — Built secure user authentication with Firebase Auth supporting sign-up, login, session management, and protected routes with authentication guards

  • Community Management — Implemented full subreddit creation and management system where authenticated users can create, customize, and moderate their own communities

  • Multi-Format Post Creation — Developed three distinct post types (text, link, and image) with proper validation, Firebase Storage integration for images, and rich content display

  • Real-Time Voting System — Built sophisticated upvote/downvote functionality for both posts and comments with real-time vote count updates and user vote tracking to prevent duplicate voting

  • Nested Comment System — Implemented threaded comment functionality with add, edit, delete operations, proper nesting structure, and user ownership verification for edit permissions

  • Post Detail Pages — Created comprehensive post view with full content display, author information, timestamps, vote counts, and integrated comment section with real-time updates

  • Multiple Feed Views — Developed dynamic post feeds with multiple sorting options (by votes descending, by latest posts) and filtering by subreddit

  • User Authorization — Implemented granular permissions system ensuring users can only edit/delete their own content while maintaining proper access control throughout the application

  • Firestore Data Architecture — Designed scalable database schema with collections for users, subreddits, posts, comments, and votes with proper relationships and query optimization

  • Responsive Design — Built mobile-first responsive interface ensuring smooth experience across all devices and screen sizes

  • Image Upload System — Integrated Firebase Storage for image uploads with progress tracking, validation, and automatic URL generation for post attachments

  • Real-Time Sync — Leveraged Firebase real-time capabilities to update vote counts, new comments, and content changes instantly across all connected clients

🛠 Tech Stack

Frontend Framework: Angular 15 with TypeScript
State Management: Angular Services and RxJS Observables
Backend Services: Firebase (BaaS)
Authentication: Firebase Authentication with JWT tokens
Database: Cloud Firestore (NoSQL)
Storage: Firebase Storage for image uploads
Hosting: Netlify with automatic deployments
Routing: Angular Router with route guards
Forms: Angular Reactive Forms with validation
HTTP Client: Angular HttpClient for API communication

🚀 Why This Project Matters

This project demonstrates my ability to:

  • Build complex, full-stack applications using modern frameworks and cloud services
  • Design and implement scalable database schemas with proper relationships in NoSQL databases
  • Handle real-time data synchronization across multiple clients
  • Implement secure authentication and authorization patterns
  • Manage complex state using Angular services and RxJS observables
  • Create intuitive user experiences for content-heavy applications
  • Write maintainable TypeScript code with proper typing and interfaces
  • Structure large-scale Angular applications with modular architecture
  • Integrate multiple Firebase services (Auth, Firestore, Storage) seamlessly

🏗 Architecture Highlights

  • Modular Angular Architecture — Organized application into feature modules with lazy loading support, shared components, and service-based architecture

  • Firebase Integration — Complete Firebase setup with:

    • Authentication service handling user sessions
    • Firestore service managing database operations
    • Storage service handling file uploads
    • Proper error handling and loading states

  • RxJS for Reactive Programming — Extensive use of Observables for asynchronous operations, real-time data streams, and event handling

  • Route Guards — Implemented authentication guards to protect routes and ensure only logged-in users can access certain features

  • Service Layer Pattern — Created dedicated services for authentication, posts, comments, subreddits, and votes with clear separation of concerns

  • Component Communication — Proper parent-child communication using Input/Output decorators and service-based state sharing

  • Firestore Query Optimization — Implemented efficient queries with proper indexing, pagination support, and minimal data fetching

  • Form Validation — Reactive forms with custom validators, real-time validation feedback, and error handling

  • TypeScript Interfaces — Strongly typed data models for User, Post, Comment, Subreddit, and Vote entities

📊 Technical Achievements

  • Angular 15 Application with modern best practices
  • Firebase Integration across Auth, Firestore, and Storage
  • Real-Time Updates using Firestore listeners
  • Nested Comment System with infinite depth support
  • Multi-Format Posts (text, link, image)
  • Vote Tracking System preventing duplicate votes
  • User Permissions with edit/delete authorization
  • Multiple Sorting Options for content feeds
  • Responsive UI working across all devices
  • Image Upload Pipeline with validation and storage
  • Production Deployed on Netlify with CI/CD

🎯 Key Technical Challenges Solved

1. Real-Time Vote Synchronization

Implemented a system where votes update instantly across all users viewing the same post, while preventing users from voting multiple times and maintaining accurate vote counts even under concurrent updates.

2. Nested Comment Threading

Built a recursive comment structure allowing unlimited nesting depth with proper rendering, edit permissions, and efficient Firestore queries to fetch comment trees.

3. Multi-Format Content Handling

Created a unified post interface supporting three different content types (text, link, image) with type-specific validation, rendering, and storage strategies.

4. Permission-Based UI

Implemented conditional rendering throughout the app showing edit/delete buttons only to content owners while maintaining security at the service layer.

5. Firebase Data Modeling

Designed a NoSQL schema balancing normalization and denormalization for optimal read/write performance in a social platform context.
