What problem does it solve?

Help teams design and operate production-ready SaaS backend services that must balance multi-tenant data isolation, secure authentication, reliable background processing, and scalable observability while avoiding common migration and performance pitfalls.

Core Features & Use Cases

• API design & conventions: RESTful patterns, response and error formats, pagination, filtering, and consistent status codes for client interoperability.
• Multi-tenancy strategies: Shared-schema, separate-schema, and separate-database tradeoffs plus row-level security and middleware examples to enforce tenant context.
• Authentication & authorization: JWT, refresh tokens, API key handling, and RBAC patterns for protecting tenant boundaries and administrative actions.
• Operational patterns: Rate limiting strategies, background job queuing and retries, safe migration steps, connection pooling, health checks, logging, metrics, and distributed tracing.
• Use Case: Architect an orders API for a multi-tenant ecommerce SaaS that requires per-tenant isolation, admin roles, webhook processing, and SLO-driven observability.

Quick Start

Design a multi-tenant REST API for an orders service that uses JWT authentication, row-level security, Redis-backed rate limiting, Celery-style background jobs, and Prometheus metrics.
