Frontend Architecture

This interface is intentionally minimal. It prioritizes observability, reliability, and clarity over visual noise. The UI exists to expose real system behavior, not to decorate it.

Architecture

Static-first delivery

Content is served as a static site from CloudFront to maximize performance and eliminate rendering risk. JavaScript is only used where data must be live.

Predictable performance by design.

Static HTML CDN caching Fast global delivery

Reliability

Failure is a first-class state

The UI is designed to display API errors, stale data, and degraded states explicitly, instead of hiding failures behind loaders or silent retries.

Mirrors real dashboard behavior in production.

Error states Timeout awareness Resilient UX

Design goals

Signal over decoration

Layout favors data density, legibility, and predictable structure over aesthetic complexity. Everything exists to support operational visibility.

This is how on-call dashboards are built.

No frameworks Accessible UI Performance-first

Source control

Frontend repository
