Experience
Continuous Delivery Tool
As a DevOps engineer, I needed more visibility of Terraform and Ansible changes by other team members. I designed and configured an internal continuous-deployment (CD) tool used by DevOps to replace Atlantis.
The purpose of the CD tool was to run checks and output the Terraform and Ansible changes to Github so that all engineers could view and be aware of the changes. Once the pull request (PR) is reviewed and approved, this will kick off the changes, and the final output will be visible. Only after a successful deployment would the PR be able to be merged into the master.

Kubernetes Rolling Upgrade Script
A script that upgrades nodes in a Kubernetes cluster. It takes a number of arguments, for example, the version to upgrade to, the cluster to upgrade, and the nodes' labels to target.
This will deploy new nodes to the cluster with the right labels for the pods to move to. When the nodes are up and running, the pods will start to be evicted and move to the new nodes. Once the pods are healthy, the old nodes will be decommissioned, and the script will be complete.

Migration of Services to a Kubernetes Cluster
As a DevOps engineer, I spearheaded migrating our CI/CD services from Jenkins to a new Kubernetes cluster, utilizing FluxCD for GitOps-based automated deployments. The goal was to streamline deployment pipelines, improve scalability, and enhance the overall reliability of our infrastructure. I comprehensively evaluated existing workflows, designed the migration strategy, and successfully executed the initial phases, including test environments.
Unfortunately, due to budget constraints, the project could not be brought to full completion under my leadership. However, I documented all processes, configurations, and steps meticulously and handed over a well-organized knowledge base to the team. This ensured a smooth transition and provided a strong foundation for the eventual completion of the migration.
