Monitoring stack for a fintech platform

January 10, 2026 · Prometheus, Grafana, Alerting

The challenge

The client had no centralized visibility into service health — issues were caught by customer complaints, not monitoring.

What I built

A full Prometheus + Grafana stack with custom exporters, SLO-based alerting routed to Slack, and on-call runbooks tied directly to each alert.

Result

Mean time to detection dropped from ~45 minutes to under 5. Incident response time overall fell by 40%.
