โœ๏ธ English Answer (STAR ๋ฐฉ์‹)

S โ€“ Situation
In a previous DevOps project, our CI/CD process was causing frequent deployment delays due to inconsistent configurations across environments.

T โ€“ Task
I was responsible for improving deployment stability and ensuring that all teams could release code reliably and consistently.

A โ€“ Action
I led the transition to GitOps by implementing ArgoCD integrated with Helm.
I standardized the deployment pipeline across multiple clusters and wrote documentation so developers could onboard quickly.
I also set up validation checks to prevent misconfigurations before deployment.

R โ€“ Result
After the transition, our deployment success rate increased by 80%, and release frequency improved significantly.
Teams were more confident in deploying, and collaboration between Dev and Ops became much smoother.
