Technical Architecture

1. Frontend:

   • React.js/Next.js with TypeScript for dynamic, responsive UIs.

   • Progressive Web App (PWA) support for offline functionality.

   • Mobile apps built with React Native (iOS/Android).

     
     

2. Backend:

   • Node.js/Python (Django/Flask) for RESTful APIs and business logic.

   • GraphQL for flexible data querying and real-time subscriptions.

   • Microservices architecture with Docker/Kubernetes orchestration.

     
     

3. Database:

   • Primary: PostgreSQL (ACID compliance, relational data).

   • Cache: Redis for high-performance session/data caching.

   • Analytics: Elasticsearch for log analysis and fast queries.

     
     

4. Cloud & Infrastructure:

   • AWS/GCP for scalable cloud hosting (EC2/Compute Engine, S3/Cloud Storage).

   • Serverless functions (AWS Lambda/Google Cloud Functions) for event-driven tasks.

   • CDN (Cloudflare/AWS CloudFront) for global content delivery.

     
     

5. Security:

   • End-to-end encryption (AES-256) and HTTPS/TLS for data in transit.

   • OAuth2/JWT for secure authentication and token management.

   • VPCs, firewalls, and regular security audits.

     
     

6. DevOps & Monitoring:

   • CI/CD pipelines (GitHub Actions/Jenkins) for automated testing/deployment.

   • Infrastructure-as-Code (Terraform) for environment consistency.

   • Monitoring: Prometheus/Grafana for metrics; Sentry for error tracking.

   
   

7. Integrations:

   • Stripe/PayPal for payments.

   • AWS S3/Google Cloud Storage for file management.

   • Webhooks and REST/GraphQL APIs for third-party services.

   
   

Key Architecture Highlights

• Scalable: Microservices, auto-scaling, and containerization.

• Real-Time: WebSocket/GraphQL subscriptions for live updates.

• Cross-Platform: Unified codebase (React Native + PWA).

• Secure: Compliance-ready with encryption and RBAC.
