Senior Flask developer. Use when building or working on Flask applications. Enforces application factory pattern and production-ready practices.
Consult this skill when designing client-server systems or API architectures. Use when traditional web/mobile applications with centralized services, clear separation between client and server responsibilities needed. Do not use when selecting from multiple paradigms - use architecture-paradigms first. DO NOT use when: peer-to-peer dominates - consider dedicated P2P patterns.
Conducts comprehensive backend design reviews covering API design quality, database architecture validation, microservices patterns assessment, integration strategies evaluation, security design review, and scalability analysis. Evaluates API specifications (REST, GraphQL, gRPC), database schemas, service boundaries, authentication/authorization flows, caching strategies, message queues, and deployment architectures. Identifies design flaws, security vulnerabilities, performance bottlenecks, and scalability issues. Produces detailed design review reports with severity-rated findings, architecture diagrams, and implementation recommendations. Use when reviewing backend system designs, validating API specifications, assessing database schemas, evaluating microservices architectures, reviewing integration patterns, or when users mention backend design review, API design validation, database design review, microservices assessment, or backend architecture evaluation.
System architect and technical design leader. Use when the user asks to talk to Winston or requests the architect.
Use when you need to design, review, or improve REST APIs with Spring Boot — including HTTP methods, resource URIs, status codes, DTOs, versioning, deprecation and sunset headers, content negotiation (JSON and vendor media types), ISO-8601 instants in DTOs, pagination/sorting/filtering, Bean Validation at the boundary, idempotency, ETag concurrency, HTTP caching, error handling, security, API documentation, controller advice, and problem details for errors.

Deliver Python backends across async FastAPI and Django or Flask service styles while keeping API design, validation, auth, and service behavior explicit.
This skill should be used when the user asks to "design REST APIs", "optimize database queries", "implement authentication", "build microservices", "review backend code", "set up GraphQL", "handle database migrations", or "load test APIs". Use for Node.js/Express/Fastify development, PostgreSQL optimization, API security, and backend architecture patterns.
Server-side architecture and security — API design, error handling, validation, logging. Use when building APIs, server logic, or reviewing backend security.
Ruby and Rails best practices for services, testing, and architecture. Use when: - Writing or reviewing Ruby/Rails code - Designing service objects or organizing business logic - Setting up RSpec tests with FactoryBot - Building APIs with JSON serialization - Optimizing Rails performance (N+1, caching) Keywords: Ruby, Rails, RSpec, FactoryBot, service object, strong params, N+1 query, Sidekiq, RuboCop, Thor CLI
Guides technical decisions, architecture, and implementation. Use for tech choices, system design, API design, refactoring, or "how should I build this" questions.
Design APIs, microservices, and database schemas. Use for server-side development, API design, or system architecture.
Backend architecture patterns and best practices for scalable server-side applications.
