4. TECHNOLOGIES AND TOOLS USED
i. Front End
1. React Native (or Flutter)
o Why? Cross-platform app development for iOS and Android using a single
codebase.
o Use: Provides fast development and ensures that the app works seamlessly on
both platforms.
2. UI/UX Design Tools
o Figma/Sketch/Adobe XD
o Why? To design wireframes and user interfaces with a focus on smooth
navigation and user experience.
o Use: Allows for collaborative design and efficient prototyping.
3. State Management
o Redux (for React Native) or Provider
o Why? Helps manage the app's state (e.g., user profiles, real-time messages)
across different components.
4. Push Notifications
o Firebase Cloud Messaging (FCM) or OneSignal
o Why? To notify users about new messages, friend requests, or events.
o Use: Both platforms offer free-tier support with robust notification
capabilities.
Backend (Server-Side)
1. Node.js + Express
o Why? Lightweight, scalable backend that handles real-time requests (such as
messaging and filtering) efficiently.
o Use: Handles API requests, real-time connections, and user management.
2. WebSocket/Socket.IO
o Why? Real-time communication between users for instant chatting.
o Use: Ensures two-way, real-time communication without the need for constant
page refreshes.
3. Database
o NoSQL: Firebase Firestore or MongoDB
Why? Easy to scale with flexible data structures for user profiles and
messages.
Use: Ideal for real-time sync (Firestore), but MongoDB is an
alternative if scalability is needed.
16 | P a g e
Relational: PostgreSQL/MySQL
o
Why? If the app requires structured data (e.g., user relationships or
match-making algorithms).
Use: Store user data, connections, and interaction logs.
4. Authentication
o Firebase Authentication or Auth0
o Why? Secure user sign-up and login via email, phone, or social media
accounts (Google, Facebook).
o Use: Handles user registration, login, and secure authentication easily.
Cloud Infrastructure
1. Firebase Hosting or Amazon Web Services (AWS)
o Why? Reliable, scalable, and cost-effective cloud platforms to host backend
services.
o Use: Firebase for quick deployment, or AWS for more control over
infrastructure.
2. Cloud Storage
o Firebase Storage or Amazon S3
o Why? To store and serve user-uploaded media (photos, videos).
o Use: Easily handles image/video storage and integrates with Firebase/Node.js
backend.
3. API Gateway
o AWS API Gateway or Express.js
o Why? Efficiently handles API requests and routes them to the appropriate
backend services.
o Use: Secure access to resources and optimizes the API call flow.
Real-Time Features
1. Push Notifications
o Firebase Cloud Messaging (FCM) or OneSignal
o Why? To notify users about new messages, activities, or friend requests.
o Use: Integrate notifications seamlessly with user actions, ensuring a real-time
experience.
2. Geo-location Services
o Google Maps API or Mapbox
o Why? To filter users based on their location (global or city-based).
o Use: Enables geo-based user filtering and proximity searches.
17 | P a g e
Security
1. SSL/TLS Encryption
o Why? Secure data transmission between the client and server.
o Use: Ensures user data is encrypted during interactions.
2. OAuth 2.0 / JWT (JSON Web Tokens)
o Why? For secure authentication and token-based session management.
o Use: Keeps users logged in securely across sessions.
Analytics & Monitoring
1. Google Analytics for Firebase
o Why? Provides insights into user behavior, app performance, and
engagement.
o Use: Tracks how users interact with the app and improves user experience.
2. Crashlytics (Firebase)
o Why? Helps monitor app crashes and performance issues.
o Use: Sends real-time reports on app health.
Optional (for Future Enhancements)
1. AI Matching Algorithm
o Technology: Python (scikit-learn) or TensorFlow
o Why? To improve user matchmaking based on interests and behavior.
o Use: Helps suggest connections based on user activity and preferences.
2. Microservices Architecture
o Why? To scale app features separately (chat service, media service, etc.).
o Use: Allows independent scaling of different modules based on load.
