🛠 Technical Architecture

Tech Stack

  • Frontend: React 18 + TypeScript, Chakra UI Design System
  • Backend: Supabase (PostgreSQL + Real-time subscriptions)
  • Authentication: Supabase Auth with multi-provider support
  • File Storage: Supabase Storage with global CDN
  • State Management: Custom React Hooks + Context API
  • Architecture Pattern: Service Layer + Repository Pattern

Key Technical Decisions

Why Supabase Over Traditional Backend?

  • Real-time capabilities out of the box for messaging and notifications
  • Row Level Security (RLS) for data privacy and security
  • Auto-generated APIs reducing development time by 60%
  • Built-in authentication with social logins
  • PostgreSQL performance for complex matching algorithms

Architecture Patterns Implemented

// Service Layer Pattern for data abstraction

const userService = {

asyncgetMatches(userId, filters) {

returnsupabase

.from(‘matches’)

.select(‘*, profiles(*)’)

.eq(‘user_id’, userId)

.match(filters);

}

};

// Custom Hooks for state management

const useRealTimeMessages = (conversationId) => {

const [messages, setMessages] =useState([]);




useEffect(() => {

constchannel=supabase

.channel(‘messages’)

.on(‘postgres_changes’, {

event:’INSERT’,

schema:’public’,

table:’messages’,

filter:`conversation_id=eq.${conversationId}`

}, (payload) => {

setMessages(prev=> […prev, payload.new]);

})

.subscribe();




return () =>channel.unsubscribe();

}, [conversationId]);




returnmessages;

};

🎨 Design System & UX

Brand Identity

  • Primary Colors: Purple (#9357A9) for trust and romance

Design Principles

  1. Mobile-First Approach – 78% of dating app usage is on mobile
  2. Accessibility-Focused – WCAG 2.1 AA compliance throughout
  3. Micro-Interactions – Subtle animations enhance user engagement
  4. Progressive Disclosure – Complex features revealed gradually

Component System


// Reusable design system components
const Button = {
variants: {
solid: { bg:’brand.500′, color:’white’ },
accent: { bg:’accent.500′, color:’white’ },
outline: { borderColor:’brand.500′, color:’brand.500′ }
},
baseStyle: {
borderRadius:’50px’,
fontWeight:’600′,
transition:’all 0.2s’
}
};

📊 User Research & Validation

Research Methods

  • User Interviews: 12 participants (ages 25-40)

Testing Strategy
// Example test coverage for critical user flows
describe(‘Matching Algorithm’, () => {
it(‘should return compatible matches based on preferences’, async () => {
constuser=createTestUser({ interests: [‘hiking’, ‘coffee’] });
constmatches=awaitgetMatches(user.id);
 
expect(matches).toHaveLength(5);
expect(matches[0].compatibility_score).toBeGreaterThan(0.8);
});
});
