Experience

Terraform App Stack

A Terraform guardrail library with all the application stack to enable the development team to deploy the application faster on the cloud provider. The company default was defined as code and made it easier to maintain and change. I wrote the tests using Terratest.

Private Cloud

Established a private cloud to host customers' applications to consume internal systems and all cloud requirements, from software to standards, to operate a dynamic environment with multiple tenants. The project was deployed to production and enabled the team to deliver applications faster.

Kubernetes On-premise Deployment

Defined and implemented an automated pipeline to deploy Kubernetes clusters on-premises without hassle. The project enabled a faster environment creation and disaster recovery as a plus; the pipeline takes care of deploying the new cluster and redeploys all apps to the cluster within an hour. Before this project, there was no way to easily redeploy clusters and applications.
