🛠️ Technical Stack

Backend (Laravel 11 + PHP 8.2)

// Product API Controller Example
class ProductController extends Controller
{
    public function index(Request $request)
    {
        $query = Product::query()
            ->when($request->category, fn($q) => $q->where('category', $request->category))
            ->when($request->search, fn($q) => $q->where('name', 'like', "%{$request->search}%"))
            ->when($request->sort, fn($q) => $q->orderBy($request->sort, $request->direction ?? 'asc'));
            
        return ProductResource::collection($query->paginate(12));
    }
}

Frontend (Angular 19 + TypeScript 5.0)

// Product Service with RxJS
@Injectable({ providedIn: 'root' })
export class ProductService {
  private apiUrl = environment.apiUrl + '/api/products';
  
  constructor(private http: HttpClient) {}
  
  getProducts(filters: ProductFilters): Observable<Product[]> {
    const params = this.buildQueryParams(filters);
    return this.http.get<Product[]>(this.apiUrl, { params });
  }
}

Database (MongoDB)

// Product Schema Example
{
  "_id": ObjectId("..."),
  "name": "Gaming Laptop RTX 4080",
  "price": 1599.99,
  "inventory": {
    "quantity": 15,
    "reserved": 3
  },
  "specifications": {
    "processor": "Intel i7-13700H",
    "graphics": "RTX 4080",
    "ram": "32GB DDR5"
  }
}

🏗️ Architecture Highlights

• RESTful API with consistent resource naming
• Real-time updates using WebSockets
• Database optimization with proper indexing
• Secure authentication with JWT tokens
• Responsive design for all device sizes

📊 Results & Impact

• Page load time: < 2 seconds average
• API response time: < 200ms for 95% of requests
• SEO score: 95/100 on Lighthouse
• 30% increase in conversion rate
• 99.9% uptime over 12 months

🚧 Challenges & Solutions

Challenge: Real-time Inventory Sync

Problem: Race conditions when multiple users add the same item to cart

Solution: Implemented optimistic locking with MongoDB’s atomic operations:

// Reserve inventory atomically
db.products.findAndModify({
  query: { 
    _id: productId, 
    "inventory.quantity": { $gte: requestedQty } 
  },
  update: { 
    $inc: { 
      "inventory.quantity": -requestedQty,
      "inventory.reserved": requestedQty 
    } 
  }
});

🔮 Future Enhancements

• AI-powered product recommendations
• Progressive Web App (PWA) capabilities
• Multi-language support with i18n
• Mobile app with React Native
