Detailed guidelines for production-grade backend development using Node.js, Express, TypeScript, and microservices. Covers layered architecture, error handling, dependency injection, validation, and observability with Sentry, Prisma, and Zod.

Orchestrate end-to-end backend feature development from requirements and architecture through implementation, testing, and production rollout with feature flags, canary releases, and monitoring.

This skill empowers you to implement secure backend coding practices, focusing on input validation, authentication, and API security. It covers vulnerability prevention, defensive programming, and secure architecture implementation. Ideal for building security-first applications that resist common attack vectors like SQL injection, XSS, and CSRF. Includes expertise in database protection, secret management, and HTTP security headers.

This skill covers backend architecture patterns, API design, and database optimization specifically for Node.js, Express, and Next.js. It provides server-side best practices for building scalable applications. Use this for designing robust backend systems and optimizing performance in modern web development environments.

This skill provides expert patterns for implementing Clerk authentication, including middleware setup, organization management, webhooks, and user synchronization. It covers sign-in, sign-up, and single sign-on (SSO) workflows for multi-tenancy scenarios. Use this for backend development tasks involving user identity management and secure access control.

A comprehensive, end-to-end workflow bundle guiding developers through the entire software development lifecycle. It covers project scaffolding, frontend development (React/Next.js), robust backend architecture, database design, rigorous testing (TDD, E2E), code quality review, and modern CI/CD deployment practices for web and mobile applications.

This skill provides expert guidance for .NET backend architecture, specializing in C#, ASP.NET Core, and enterprise patterns. It covers design, optimization, testing, and deployment strategies for production-grade APIs and microservices. Use it for architectural decisions, code review, and implementing best practices in .NET development environments.

This skill guides the development of production-grade APIs, MCP servers, and enterprise backends using modern C#/.NET best practices. It covers essential architectural components such as dependency injection (DI), advanced caching strategies (e.g., Redis), data access optimization with EF Core/Dapper, and implementing resilience patterns, ensuring robust and scalable software design.

Master building high-performance asynchronous APIs using FastAPI, SQLAlchemy 2.0, and Pydantic V2. Covers microservices, WebSockets, security, testing, and deployment strategies for production-ready Python backend systems. Includes async patterns, database optimization, and observability.

Master Firebase backend services including Authentication, Firestore, Realtime Database, Cloud Functions, Storage, and Hosting. Learn security rules, data modeling for read-heavy workloads, and cost optimization to avoid pitfalls like expensive reads and query limitations.

Build mobile and web backends using Firebase managed services including Auth, Firestore, and Cloud Functions. Ideal for serverless APIs, real-time data sync, and rapid prototyping with minimal backend code.

This skill orchestrates full-stack feature development across backend, frontend, and infrastructure layers using an API-first approach. It guides users through architecture design, parallel implementation, and integration testing phases, ensuring cohesive system delivery with modern best practices and verification steps.
