-# Suggestions for Senior-Level Improvements
+# Senior-Level Improvements
 
-## Testing Improvements
-- **Unit Testing with Jest/RTL**
-  - Gain: Catch bugs early, ensure component behavior, easier refactoring
-  - Example: Test hooks like useProductFilters in isolation
+## 1. Architecture & State Management
+
+### Global State Management
+- **Replace Context API with Redux Toolkit or Zustand**
+  - Gain: Better state management, dev tools, middleware support
+  - Example: Move cart state to Redux with proper slices and actions
+
+```typescript
+// Example Redux slice for cart
+const cartSlice = createSlice({
+  name: 'cart',
+  initialState,
+  reducers: {
+    addToCart: (state, action) => {
+      // Immutable state updates with Redux Toolkit
+    },
+    removeFromCart: (state, action) => {
+      // Automatic handling of immutability
+    }
+  }
+});
+```
+
+### Service Layer
+- **API Abstraction**
+  - Gain: Better separation of concerns, easier testing and maintenance
+  - Example: Create dedicated service classes for API operations
+
+```typescript
+class ProductService {
+  private api: ApiClient;
   
-- **Visual Regression Testing**
-  - Gain: Catch unintended UI changes, ensure consistent design
-  - Example: Compare screenshots before/after changes to ProductCard
+  async getProducts(filters: ProductFilters): Promise<Product[]> {
+    // Centralized error handling and response mapping
+  }
+}
+```
+
+## 2. Performance Optimizations
+
+### Code Splitting
+- **Dynamic Imports**
+  - Gain: Smaller initial bundle size, faster page loads
+  - Example: Lazy load product filters on mobile
+
+```typescript
+const ProductFilters = dynamic(() => import('./ProductFilters'), {
+  loading: () => <FiltersSkeleton />,
+  ssr: false
+});
+```
+
+### Caching Strategy
+- **Apollo Client Caching**
+  - Gain: Faster data access, reduced server load
+  - Example: Implement field-level caching policies
+
+```typescript
+const cache = new InMemoryCache({
+  typePolicies: {
+    Product: {
+      fields: {
+        price: {
+          read(price) {
+            // Custom cache reading logic
+          }
+        }
+      }
+    }
+  }
+});
+```
+
+## 3. Testing & Quality Assurance
+
+### Unit Testing
+- **Jest/React Testing Library**
+  - Gain: Catch bugs early, ensure component behavior
+  - Example: Test hooks like useProductFilters in isolation
+
+```typescript
+describe('useProductFilters', () => {
+  it('should filter products by price range', () => {
+    const { result } = renderHook(() => useProductFilters());
+    act(() => {
+      result.current.setPriceRange([10, 50]);
+    });
+    expect(result.current.filterProducts(mockProducts)).toEqual(
+      expect.arrayContaining([
+        expect.objectContaining({ price: expect.any(Number) })
+      ])
+    );
+  });
+});
+```
+
+### E2E Testing
+- **Expand Playwright Tests**
+  - Gain: Ensure critical user flows work end-to-end
+  - Example: Add comprehensive checkout flow testing
 
-- **Performance Testing**
-  - Gain: Monitor and maintain site speed, identify bottlenecks
-  - Example: Set Lighthouse score thresholds in CI
+```typescript
+test('complete checkout process', async ({ page }) => {
+  await page.goto('/');
+  await page.click('[data-testid="product-card"]');
+  await page.click('[data-testid="add-to-cart"]');
+  // Test entire checkout flow
+});
+```
 
-## Error Handling
-- **Error Boundaries**
-  - Gain: Graceful failure handling, better user experience
-  - Example: Fallback UI for failed product loads
+## 4. WooCommerce Integration Enhancements
 
-- **Error Tracking**
-  - Gain: Better debugging, understand user issues
-  - Example: Integration with error tracking service
+### Session Management
+- **Improve WooCommerce Session Handling**
+  - Gain: Better cart persistence, reduced errors
+  - Example: Enhanced session token management
 
-## Developer Experience
+```typescript
+// Enhanced WooCommerce session middleware
+const enhancedMiddleware = new ApolloLink((operation, forward) => {
+  const session = getWooSession();
+  if (session && !isExpired(session)) {
+    operation.setContext({
+      headers: {
+        'woocommerce-session': `Session ${session.token}`
+      }
+    });
+  }
+  return forward(operation);
+});
+```
+
+### Cart Improvements
+- **Enhanced Cart Features**
+  - Gain: Better user experience with cart functionality
+  - Example: Add cart total, copy billing address to shipping
+
+## 5. Developer Experience
+
+### Documentation
 - **Storybook Integration**
   - Gain: Better component documentation, easier UI development
   - Example: Document all variants of ProductCard
 
-- **Stricter TypeScript**
-  - Gain: Catch more bugs at compile time, better maintainability
+```typescript
+// ProductCard.stories.tsx
+export const WithDiscount = {
+  args: {
+    product: {
+      name: 'Test Product',
+      price: '100',
+      salePrice: '80',
+      onSale: true
+    }
+  }
+};
+```
+
+### TypeScript Improvements
+- **Stricter Configuration**
+  - Gain: Catch more bugs at compile time
   - Example: Enable strict mode, add proper generics
 
-## Performance
-- **Code Splitting**
-  - Gain: Faster initial load, better resource utilization
-  - Example: Lazy load product filters on mobile
+```typescript
+// tsconfig.json improvements
+{
+  "compilerOptions": {
+    "strict": true,
+    "noUncheckedIndexedAccess": true,
+    "exactOptionalPropertyTypes": true
+  }
+}
+```
+
+## 6. Monitoring & Analytics
+
+### Error Tracking
+- **Sentry Integration**
+  - Gain: Better error tracking, faster bug fixing
+  - Example: Add proper error boundaries with Sentry
+
+```typescript
+class ErrorBoundary extends React.Component {
+  componentDidCatch(error, errorInfo) {
+    Sentry.captureException(error, { extra: errorInfo });
+  }
+}
+```
+
+### Performance Monitoring
+- **Core Web Vitals**
+  - Gain: Track and improve user experience metrics
+  - Example: Implement proper performance monitoring
+
+## 7. Code Quality & Maintainability
+
+### Design Patterns
+- **Implement Factory Pattern**
+  - Gain: Better code organization, easier maintenance
+  - Example: Create product factory for different types
+
+```typescript
+class ProductFactory {
+  createProduct(type: ProductType, data: ProductData): Product {
+    switch (type) {
+      case 'simple':
+        return new SimpleProduct(data);
+      case 'variable':
+        return new VariableProduct(data);
+      default:
+        throw new Error(`Unknown product type: ${type}`);
+    }
+  }
+}
+```
+
+### Code Organization
+- **Feature-based Structure**
+  - Gain: Better code organization, easier navigation
+  - Example: Reorganize code by feature instead of type
+
+```
+src/
+  features/
+    products/
+      components/
+      hooks/
+      services/
+      types/
+    cart/
+      components/
+      hooks/
+      services/
+      types/
+```
+
