Why
For a cost-sensitive company, a paid observability SaaS is a recurring tax that grows with your data. At $815/month and climbing, New Relic was the obvious candidate to replace once the team had the Kubernetes muscle to run its own stack.
What I built
A self-hosted LGTM stack on Kubernetes: Loki (logs), Grafana (visualization), Tempo (traces), Mimir (metrics). Migrated all three signals off New Relic, then built unified dashboards covering application performance, logs, and deployments in one place.
Outcome
~50% cost reduction, better log retention, and more query flexibility than the managed product it replaced.
