Tips for Using This Prompt

  • Architecture First: This is a design-focused prompt. Focus on system architecture, data models, API contracts, and infrastructure design rather than implementation code.

  • Scalability Planning: Design for growth from day one. Consider caching strategies, database indexing, async processing, and horizontal scaling capabilities.

  • Security by Design: Implement security at every layer - authentication, authorization, data encryption, input validation, rate limiting, and GDPR compliance.

  • Observability First: Build comprehensive logging, tracing, and metrics collection from the start. Use correlation IDs to track requests across distributed systems.

  • Infrastructure as Code: Use Terraform to define all AWS resources, enabling version control, code review, and reproducible deployments across environments.
