Architects and manages SQL databases using the Sequelize ORM with type-safe model definitions and robust transaction handling.
This skill equips Claude with the expertise to implement and maintain relational database layers using the Sequelize ORM. It provides standardized implementation patterns for TypeScript-integrated models, complex associations, and managed transactions to ensure data integrity. By enforcing best practices like eager loading to prevent N+1 queries and the use of 'declare' for property safety, this skill helps developers build scalable, high-performance backends for PostgreSQL, MySQL, SQLite, and more.
