Backend Migrations

Acerca de

This skill empowers developers to safely evolve database architectures by automating the creation and management of versioned migration scripts across various frameworks. It focuses on maintaining high availability through zero-downtime deployment patterns, ensuring every schema change includes robust rollback support and backwards compatibility. Whether adding indexes to high-traffic tables or restructuring core schemas, it provides the structural guidance needed to prevent data loss and minimize service interruptions during production deployments.
