backend-and-data-architecture

What problem does it solve?

Production-grade backend and data architecture decisions are often underdefined, leading to brittle contracts, confusing data models, and difficult operability under real traffic and outages. This Skill provides expert guidance to establish contracts, design durable data models, plan migrations, and implement resilient, observable systems.

Core Features & Use Cases

• Contract-first design: define APIs, boundaries, and data contracts before implementing the system.
• Data modeling and migrations: guidance on schema evolution, versioning, backfills, and rollback safety.
• Resilience and observability: patterns for timeouts, retries, dead-lettering, metrics, and tracing to ensure production readiness.
• Operability and rollout readiness: guidance on release gates, validation checks, rollback plans, and incident response.

Quick Start

Provide a concise plan outlining backend contracts, data models, and resilience goals for production-ready systems.
