Exploring new opportunities

I automate software delivery with Jenkins, Ansible and ArgoCD, on-premise and in the cloud, and I'm building self-hosted AI agents that run tasks with a human in the loop.

About

I make shipping to production a non-event.

I'm Phearak, a DevOps Engineer focused on Continuous Integration and Continuous Delivery (CI/CD) — helping teams move code from commit to a reliable, running service.

I use Jenkins to handle CI and Ansible and Argo CD to deliver applications into Kubernetes environments. For smaller projects, I keep things simple with Jenkins and Ansible pipelines. For larger projects, Jenkins handles CI while Argo CD takes care of continuous delivery, ensuring that the cluster state stays aligned with Git and making rollbacks as simple as reverting a change.

Before becoming a DevOps Engineer, I spent time writing code during university and later while working at a ministry. That experience gave me an understanding of how developers think, build, and troubleshoot software, which has shaped the way I approach DevOps today.

More recently, I've been building a DevOps AI agent to help with my day-to-day tasks. It can connect to servers and execute tasks with explicit human approval, integrate with different monitoring tools, and access a knowledge base of internal documentation. The AI runs entirely in-house, keeping internal data within our own network while helping me troubleshoot issues, find information, and manage infrastructure more efficiently.
