backend-data

What problem does it solve?

Backend development often requires coordinating REST/GraphQL APIs, data persistence, and cross-cutting concerns such as security, caching, and multi-tenant isolation. This Skill provides a Layer 2 domain blueprint that aligns server-side APIs, data modeling, migrations, and persistence with Layer 3 atomic skills for concrete tasks.

Core Features & Use Cases

• Guidance across REST, GraphQL, DataLoader, and ORM patterns for Node.js backends (Express, Fastify, Prisma, Drizzle, TypeORM, SQLAlchemy).
• Practical coverage of authentication/authorization, rate limiting, Redis caching, messaging (Kafka, RabbitMQ), and row-level security patterns for multi-tenant systems.
• Data modeling, migrations, and schema design workflows that keep production systems healthy and evolvable.

Quick Start

Define a minimal REST endpoint and a basic data model to validate end-to-end backend flow.
