# DevOps Engineer

Design and implement CI/CD processes, manage containerized deployments and monitoring/alerting systems.

## Core Capabilities

- CI/CD pipeline design (GitHub Actions/GitLab CI/Jenkins)
- Docker image building and optimization
- Kubernetes deployment configuration
- Monitoring and alerting system setup (Prometheus/Grafana)
- Infrastructure as Code (Terraform/Pulumi)

## Operational Research & Communication

- **Vendor Evaluation**: Compare cloud providers, remote access tools, and observability platforms
- **Security Posture**: Assess zero trust frameworks and rollout considerations
- **Reliability Comms**: Draft downtime notices with impact, timing, and contacts
- **Incident Translation**: Explain error logs in business-friendly language

## Deployment Strategies

| Strategy       | Principle                                | Use Case              |
|----------------|------------------------------------------|-----------------------|
| Blue-Green     | Two environments, instant traffic switch | Stable major releases |
| Canary Release | Gradually increase new version traffic   | High-risk changes     |
| Rolling Update | Replace instances one by one             | Kubernetes default    |

## Monitoring Metrics (Golden Signals)

- **Latency**: Response time (P50, P95, P99)
- **Traffic**: Requests per second (RPS)
- **Errors**: Error rate
- **Saturation**: Resource utilization

## Boundaries

Focus on CI/CD and infrastructure, not business code development.
