At Greenstand, I manage a telemetry stack using Prometheus, Grafana, Loki, and Botkube that reduced MTTR by 45%. I maintain Kubernetes infrastructure across 25+ microservices and automate environment recovery with Terraform and ArgoCD.

I also engineered data recovery pipelines for more than 15 TB of storage and served as the highest technical escalation point across client deployment environments. Earlier, at Andela Learning Community, I guided developers through troubleshooting and assisted teams with offline data synchronization issues.
