senior-backend: Скилл для разработки масштабируемых бэкендов

--- name: senior-backend description: Comprehensive backend development skill for building scalable backend systems using NodeJS, Express, Go, Python, Postgres, GraphQL, REST APIs. Includes API scaffolding, database optimization, security implementation, and performance tuning. Use when designing APIs, optimizing database queries, implementing business logic, handling authentication/authorization, or reviewing backend code. --- # Senior Backend Complete toolkit for senior backend with modern tools and best practices. ## Quick Start ### Main Capabilities This skill provides three core capabilities through automated scripts: ```bash # Script 1: Api Scaffolder python3 ~/.{TOOL}/skills/senior-backend/scripts/api_scaffolder.py [options] # Script 2: Database Migration Tool python3 ~/.{TOOL}/skills/senior-backend/scripts/database_migration_tool.py [options] # Script 3: Api Load Tester python3 ~/.{TOOL}/skills/senior-backend/scripts/api_load_tester.py [options] ``` ## Core Capabilities ### 1. Api Scaffolder Automated tool for api scaffolder tasks. **Features:** - Automated scaffolding - Best practices built-in - Configurable templates - Quality checks **Usage:** ```bash python3 ~/.{TOOL}/skills/senior-backend/scripts/api_scaffolder.py <project-path> [options] ``` ### 2. Database Migration Tool Comprehensive analysis and optimization tool. **Features:** - Deep analysis - Performance metrics - Recommendations - Automated fixes **Usage:** ```bash python3 ~/.{TOOL}/skills/senior-backend/scripts/database_migration_tool.py <target-path> [--verbose] ``` ### 3. Api Load Tester Advanced tooling for specialized tasks. **Features:** - Expert-level automation - Custom configurations - Integration ready - Production-grade output **Usage:** ```bash python3 ~/.{TOOL}/skills/senior-backend/scripts/api_load_tester.py [arguments] [options] ``` ## Reference Documentation ### Api Design Patterns Comprehensive guide available in `references/api_design_patterns.md`: - Detailed patterns and practices - Code examples - Best practices - Anti-patterns to avoid - Real-world scenarios ### Database Optimization Guide Complete workflow documentation in `references/database_optimization_guide.md`: - Step-by-step processes - Optimization strategies - Tool integrations - Performance tuning - Troubleshooting guide ### Backend Security Practices Technical reference guide in `references/backend_security_practices.md`: - Technology stack details - Configuration examples - Integration patterns - Security considerations - Scalability guidelines ## Tech Stack **Languages:** TypeScript, JavaScript, Python, Go, Swift, Kotlin **Frontend:** React, Next.js, React Native, Flutter **Backend:** Node.js, Express, GraphQL, REST APIs **Database:** PostgreSQL, Prisma, NeonDB, Supabase **DevOps:** Docker, Kubernetes, Terraform, GitHub Actions, CircleCI **Cloud:** AWS, GCP, Azure ## Development Workflow ### 1. Setup and Configuration ```bash # Install dependencies npm install # or pip install -r requirements.txt # Configure environment cp .env.example .env ``` ### 2. Run Quality Checks ```bash # Use the analyzer script python3 ~/.{TOOL}/skills/senior-backend/scripts/database_migration_tool.py . # Review recommendations # Apply fixes ``` ### 3. Implement Best Practices Follow the patterns and practices documented in: - `references/api_design_patterns.md` - `references/database_optimization_guide.md` - `references/backend_security_practices.md` ## Best Practices Summary ### Code Quality - Follow established patterns - Write comprehensive tests - Document decisions - Review regularly ### Performance - Measure before optimizing - Use appropriate caching - Optimize critical paths - Monitor in production ### Security - Validate all inputs - Use parameterized queries - Implement proper authentication - Keep dependencies updated ### Maintainability - Write clear code - Use consistent naming - Add helpful comments - Keep it simple ## Common Commands ```bash # Development npm run dev npm run build npm run test npm run lint # Analysis python3 ~/.{TOOL}/skills/senior-backend/scripts/database_migration_tool.py . python3 ~/.{TOOL}/skills/senior-backend/scripts/api_load_tester.py --analyze # Deployment docker build -t app:latest . docker-compose up -d kubectl apply -f k8s/ ``` ## Troubleshooting ### Common Issues Check the comprehensive troubleshooting section in `references/backend_security_practices.md`. ### Getting Help - Review reference documentation - Check script output messages - Consult tech stack documentation - Review error logs ## Resources - Pattern Reference: `references/api_design_patterns.md` - Workflow Guide: `references/database_optimization_guide.md` - Technical Guide: `references/backend_security_practices.md` - Tool Scripts: `scripts/` directory
