From blind spots to full observability

The challenge

The team was flying partially blind. When something broke, engineers pieced together what happened from scattered logs and customer reports. There was no shared picture of system health and no early warning before incidents hit users.

What I built

• Unified telemetry. Standardized metrics, structured logs, and distributed tracing across every service, flowing into one place.
• Dashboards that matter. Service-level dashboards built around the golden signals — latency, traffic, errors, saturation — not vanity graphs.
• Actionable alerting. Alerts tied to user-facing symptoms and error budgets, with clear runbooks, so on-call knows what to do at 3am.
• Healthchecks everywhere. Liveness and readiness probes plus synthetic checks that catch failures before customers do.

The outcome

Mean time to detection fell from hours to minutes. The team shifted from reactive firefighting to proactively catching issues, and every new service now ships observable by default.
