Key Challenges & Solutions

1. Balancing Performance with Brand Experience

Challenge:

Building bespoke UI/UX that conveyed high-stakes excitement while preserving usability required adopting a modular frontend architecture.

Solution:

We implemented a component-driven design system using modern frameworks optimized for performance and scalability:

// Reusable game card component with optimized rendering
interface GameCardProps {
  game: Game;
  onPlay: (gameId: string) => void;
  isFavorite?: boolean;
}

const GameCard: React.FC<GameCardProps> = ({ game, onPlay, isFavorite }) => {
  return (
    <Card className="game-card" data-testid="game-card">
      <LazyImage 
        src={game.thumbnail} 
        alt={game.title}
        placeholder={<Skeleton />}
      />
      <CardContent>
        <Typography variant="h6">{game.title}</Typography>
        <Typography variant="body2">{game.provider}</Typography>
        <Button 
          variant="primary" 
          onClick={() => onPlay(game.id)}
        >
          Play Now
        </Button>
        {isFavorite && <FavoriteIcon />}
      </CardContent>
    </Card>
  );
};

Results:

• Consistent brand experience across all pages
• Fast page loads and smooth animations
• Easy maintenance and feature additions
• Responsive design working seamlessly on all devices

2. High-Throughput Backend Architecture

Challenge:

To support large volumes of concurrent gameplay and wallet transactions, the backend required exceptional scalability and fault tolerance at the core.

Solution:

Implemented microservices-ready API layers with:

• Careful database schema design
• Efficient caching strategies
• Load balancing and horizontal scaling

Architecture:

┌──────────────────────────────────────┐
│        Load Balancer (Nginx)         │
└─────────────┬────────────────────────┘
              │
    ┌─────────┴─────────┐
    │                   │
┌───▼────────┐  ┌──────▼───────┐
│  API Node  │  │  API Node    │
│  Cluster   │  │  Cluster     │
└───┬────────┘  └──────┬───────┘
    │                   │
┌───▼──────────────────▼────┐
│    Redis Cache Layer       │
└───┬────────────────────────┘
    │
┌───▼──────────────────┐
│  PostgreSQL Cluster  │
│  (Primary + Replicas)│
└──────────────────────┘

Key Features:

• Connection pooling for database efficiency
• Redis for session management and hot data
• Asynchronous job queues for heavy operations
• Database read replicas for query optimization

Results:

• Low latency responses even under load
• Ability to handle thousands of concurrent users
• Zero downtime during traffic spikes
• Graceful degradation under extreme load

3. Secure & Reliable Transaction Processing

Challenge:

Although leveraging third-party gateways for payments, we needed to design internal services for managing transactional workflows, concurrency control, audit trails, and compliance verification.

Solution:

Built a secure transaction processing system with:

// Transaction processing with audit trail
class TransactionProcessor {
  async processDeposit(userId: string, amount: number, currency: string) {
    const transaction = await this.db.transaction();
    
    try {
      // Verify user and compliance checks
      await this.verifyUser(userId, transaction);
      await this.checkComplianceLimits(userId, amount, transaction);
      
      // Process payment through gateway
      const paymentResult = await this.paymentGateway.charge({
        userId,
        amount,
        currency
      });
      
      if (!paymentResult.success) {
        throw new PaymentError('Payment gateway failed');
      }
      
      // Update wallet balance
      await this.walletService.credit(userId, amount, currency, transaction);
      
      // Create audit log (cryptographically secure)
      await this.auditLog.record({
        userId,
        action: 'DEPOSIT',
        amount,
        currency,
        timestamp: new Date(),
        paymentId: paymentResult.id,
        signature: this.generateSignature(paymentResult)
      }, transaction);
      
      // Commit transaction
      await transaction.commit();
      
      // Notify user
      await this.notificationService.send(userId, 'deposit_success', { amount });
      
      return { success: true, balance: await this.walletService.getBalance(userId) };
      
    } catch (error) {
      await transaction.rollback();
      await this.handleTransactionError(userId, error);
      throw error;
    }
  }
  
  private generateSignature(data: any): string {
    return crypto
      .createHmac('sha256', process.env.AUDIT_SECRET!)
      .update(JSON.stringify(data))
      .digest('hex');
  }
}

Security Features:

• Cryptographically secure audit trails
• Automatic rollback on failures
• Compliance verification at every step
• Encrypted sensitive data storage
• Role-based access controls

Results:

• 100% transaction traceability
• Zero financial discrepancies
• Full regulatory compliance
• Instant fraud detection capabilities

4. Multicurrency Wallet Support

Challenge:

To maximize accessibility, both fiat and crypto transactions were supported.

Solution:

We integrated:

• Coinspaid for crypto onboarding and settlement
• PaymentIQ for fiat channel support

This enabled seamless balance conversions and multi-currency operations with real-time exchange rates.

Implementation Features:

• Real-time currency conversion
• Support for major cryptocurrencies (BTC, ETH, USDT, etc.)
• Fiat currencies (EUR, USD, GBP, etc.)
• Secure wallet management
• Automatic exchange rate updates
• Multi-wallet support per user

5. Third-Party Sync and Gaming Integration

Challenge:

Real-time synchronization with gaming content providers and ancillary services required resilient API orchestration, webhook processing, and error-tolerant message queues.

Solution:

Built a robust integration layer handling:

Gaming Providers:

• SOFTSWISS - Slot and table games
• Alea - Live casino content

Support Services:

• KYC via Sumsub - Identity verification
• Email services via Sendpost - Transactional emails
• Analytics and reporting integrations

Technical Implementation:

// Game provider aggregation
class GameAggregator {
  private providers: Map<string, GameProvider>;
  
  async fetchGames(filters?: GameFilters): Promise<Game[]> {
    const providerGames = await Promise.allSettled(
      Array.from(this.providers.values()).map(provider =>
        provider.getGames(filters).catch(error => {
          this.logger.error(`Provider ${provider.name} failed`, error);
          return [];
        })
      )
    );
    
    // Combine results from all providers
    const allGames = providerGames
      .filter(result => result.status === 'fulfilled')
      .flatMap(result => result.value);
    
    // Normalize and cache
    return this.normalizeGames(allGames);
  }
  
  async launchGame(gameId: string, userId: string): Promise<GameSession> {
    const game = await this.findGame(gameId);
    const provider = this.providers.get(game.providerId);
    
    if (!provider) {
      throw new Error('Provider not available');
    }
    
    // Create session with provider
    const session = await provider.createSession(userId, gameId);
    
    // Track session locally
    await this.sessionTracker.create(session);
    
    return session;
  }
}

Results:

• Seamless game integration from multiple providers
• Error handling prevents cascade failures
• Webhook processing for real-time updates
