Proposal: Application Health Check Endpoint

I can implement a health monitoring endpoint for deployment and observability.

Work:

• Add GET /health endpoint
• Report service status (ok / degraded / error)
• Check database connectivity in real time
• Include dependency status in response (e.g., DB, cache if present)
• Ensure lightweight execution for monitoring systems

Deliverables:

• Health check API endpoint
• DB connectivity validation
• Structured JSON response for monitoring tools
• Ready for deployment probes (Kubernetes / CI health checks)

Goal:
Provide reliable service and dependency status visibility for production monitoring.

I'd like to take this issue. I have experience building production-ready backend services with health monitoring, dependency checks, and deployment observability. I can implement a robust health check endpoint that reports application status, verifies database connectivity, and provides reliable signals for monitoring and uptime checks.
