Backend Development Skill

Production-ready backend development with modern technologies, best practices, and proven patterns.

When to Use

• Designing RESTful, GraphQL, or gRPC APIs
• Building authentication/authorization systems
• Optimizing database queries and schemas
• Implementing caching and performance optimization
• OWASP Top 10 security mitigation
• Designing scalable microservices
• Testing strategies (unit, integration, E2E)
• CI/CD pipelines and deployment
• Monitoring and debugging production systems

Technology Selection Guide

Languages: Node.js/TypeScript (full-stack), Python (data/ML), Go (concurrency), Rust (performance) Frameworks: NestJS, FastAPI, Django, Express, Gin Databases: PostgreSQL (ACID), MongoDB (flexible schema), Redis (caching) APIs: REST (simple), GraphQL (flexible), gRPC (performance)
