Built a complete observability stack from scratch with SLO-driven alerting, reducing MTTR by 90% and eliminating alert fatigue.
The company had zero monitoring beyond basic health checks. Production issues were discovered by customers, MTTR averaged 4 hours, and the on-call team was drowning in noise from hundreds of misconfigured CloudWatch alarms. There was no distributed tracing across their 60+ microservices.
We deployed Prometheus for metrics, Grafana for visualization, Loki for log aggregation, and Tempo for distributed tracing. Defined 15 SLOs with error budgets tied to business KPIs, implemented SLO-driven alerting that replaced all legacy alarms, and built runbooks for every alert.
