Hello 👋.

I'm DeX Days.

Passionate about building scalable cloud infrastructure, automating everything, and enabling teams to ship faster. Specializing in AWS, Kubernetes, Terraform, and modern CI/CD.

About Me

Who I Am

I'm a DevOps & Cloud Engineer with a passion for building resilient, scalable systems. I help teams move faster and ship more reliably by automating infrastructure, optimizing CI/CD pipelines, and adopting cloud-native practices.

My experience spans AWS, GCP, and Azure, with deep expertise in containerization and orchestration using Docker and Kubernetes. I believe in infrastructure as code, GitOps workflows, and the power of observability.

When I'm not architecting cloud solutions, I'm contributing to open source, writing about DevOps practices, or exploring new tools in the cloud-native ecosystem.

Projects

What I've Built

Open-source tools, templates, and infrastructure projects.

Homelab Infrastructure

A 3-node Proxmox cluster running K3s, Prometheus/Grafana, GitLab, and 30+ self-hosted services — where every production skill was first broken and fixed before it ever touched a real deployment.

GitOps Platform with ArgoCD

A production-grade GitOps platform built on ArgoCD with multi-environment promotion, automated rollbacks, Slack notifications, and compliance guardrails.

Why It Matters

This lab is where theory meets practice. Every tool on my resume — Kubernetes, Terraform, Prometheus, GitOps — was first deployed, broken, fixed, and optimized here before ever touching production. It's also where I run the personal services my family relies on, so maintenance discipline comes naturally.
