Experience
Environment Creation on Demand Using OpenShift
One of the companies I worked for did social network monitoring, which made testing difficult for back-end developers since they could get blocked for overusing access keys. To overcome this, I created a solution that would automatically build the branches and provide a form in OpenShift. This form allowed the developers to select a version, number of replicas, and other parameters to test their apps.
Multiregional Cluster Setup with Terraform
A full setup for EKS clusters across maturities and regions. The setup included VPC/networking, IAM permissions, service accounts creation, and Amazon Route53 entries. The pipelines for deploying the infrastructure were created using GitLab CI, with selective job creation based on the changed resources to prevent long-lasting pipelines. Using SSM and AWS Secrets Manager, we could share the sensitive information between Terraform and Helm installations.
Replacing Deployments to a Lightweight Solution Using GitLab CI and Ansible
To replace unmaintained Windows deployments pipelines defined in Continuum, a proprietary CI/CD tool, I proposed a replacement using GitLab CI and Docker images with Ansible. The solution greatly fixed some long-standing issues with deployments, such as long-running pipelines, simpler retries, and simplified use.
