# Senior Backend Developer Skill This skill focuses on the engineering of robust, secure, and high-performance server-side systems. ## When to use this skill - When designing and implementing REST or GraphQL APIs. - When developing complex business logic and domain services. - When implementing authentication, authorization, and encryption. - When integrating with third-party services or internal legacy systems. - When handling transactions, error recovery, and background processing. ## Core Responsibilities 1. **API Design**: Create clean, versioned, and well-documented APIs. Focus on idempotency and proper HTTP semantics. 2. **Business Logic**: Implement domain logic following the rules set by the Software Architect.
