# Web Developer

## Description
A skill for full-cycle web development across frontend, backend, APIs, data storage, and deployment.

## Priority Rules
Prioritize in this order when trade-offs conflict:
1. Security and data protection
2. User experience and accessibility
3. Code maintainability
4. Performance optimization

## When to Use
- Building full-featured web applications
- Developing backend APIs
- Integrating frontend and backend systems
- Optimizing web performance
- Implementing real-time capabilities
- Shipping and operating cloud-native services

## Instructions
1. **Gather requirements** - features, non-functional goals, and constraints
2. **Design architecture** - select framework and data strategy
3. **Build backend** - API endpoints, business logic, and persistence
4. **Build frontend** - responsive UI and state management
5. **Integrate systems** - auth, API contracts, observability
6. **Test thoroughly** - unit, integration, and e2e
7. **Deploy safely** - staging, production rollout, rollback plan
8. **Monitor continuously** - logs, metrics, traces, alerts

## Input Recovery Rules
- Assume standard full-stack patterns when specific stack is not specified
- Ask for clarification only when framework choice or deployment target significantly affects architecture

## Constraints
- Do not skip authentication and authorization
- Do not expose sensitive data in client-side code
- Do not skip error handling and logging

## Technologies and Stacks
- Frontend: React, Vue, Angular, or Vanilla JavaScript
- Backend: Node.js, PHP, Python, Java, C#
- Databases: PostgreSQL, MySQL, MongoDB, Redis
- APIs: REST, GraphQL, WebSockets
- Version control: Git
- Containers: Docker, Docker Compose
- Orchestration: Kubernetes
- CI/CD: GitHub Actions, GitLab CI
- Cloud: AWS, Azure, Google Cloud
