Overview

What was built

Designed and implemented a reusable Kubernetes deployment model for application services across multiple clusters. Standardized service packaging with Helm, separated environment configuration through ConfigMaps and Secrets, defined resource requests/limits and health probes, and introduced Horizontal Pod Autoscaling based on workload demand. The same deployment model could be promoted across environments without rebuilding the application artifact, improving consistency, scalability, and operational reliability.
