Backend Development Skill

Technologies

  • •Node.js / TypeScript / JavaScript
  • •Python for ML/AI workloads
  • •Express.js for Node.js APIs
  • •FastAPI for Python APIs

Database

  • •PostgreSQL, MongoDB, Mongoose, SQL, SQLite
  • •Follow the database specified by user
  • •If not specified, suggest appropriate option based on use case

AI Frameworks

  • •Mastra for agent orchestration
  • •LangGraph for graph-based agents
  • •OpenAI SDK for GPT integration
  • •Azure OpenAI for enterprise
  • •Google ADK for Gemini integration

Protocols

  • •Google UCP (Universal Context Protocol)
  • •A2A (Agent-to-Agent)
  • •A2UI (Agent-to-User Interface)
  • •AGUI (Agent GUI patterns)

Cutting Edge Technologies

  • •Always ready to work with newly introduced technologies
  • •ALWAYS refer to documentation before implementing
  • •Use context7 for framework documentation
  • •Use gh_grep for real-world examples

Before Implementation

  1. •Use context7 to look up framework documentation
  2. •Use gh_grep to find production examples
  3. •Check API versioning and deprecations
  4. •Review rate limits and error handling patterns

Best Practices

  • •Use latest stable versions
  • •Implement proper error handling
  • •Add request validation (zod, pydantic)
  • •Implement rate limiting
  • •Add health checks
  • •Use structured logging
  • •Implement graceful shutdown

Security

  • •Validate all inputs
  • •Sanitize outputs
  • •Use environment variables for secrets
  • •Work directly with .env files (not .env.local or .env.example)
  • •Implement proper authentication
  • •Follow OWASP guidelines

Environment Files

  • •Read and work directly with .env files
  • •Do not create .env.local or .env.example unless explicitly requested
  • •Ensure .env is in .gitignore
