## Proximos Pasos Recomendados

1. **Backend Integration (P1)**
   - Implementar API de upload de videos
   - Configurar S3/CloudFront para almacenamiento
   - Crear WebSocket server para live streaming

2. **Services (P1)**
   - `video.service.ts` - Upload, processing, streaming
   - `certificate.service.ts` - PDF generation
   - `creator.service.ts` - Stats, courses management

3. **Store Integration (P2)**
   - Agregar slices a `educationStore` para creators
   - WebSocket hooks para chat en tiempo real

4. **Testing (P3)**
   - Unit tests para componentes
   - Integration tests con mock APIs
