Hey, I'm Alex 👋

Digital Producer with 14+ years in multimedia and design, transitioning into DevOps engineering. I bring systems thinking from a production background, understanding how things are built, delivered, and maintained, and I'm applying that to infrastructure, automation, and deployment pipelines.


What I'm Working On

  • Building a DevOps learning path hands-on: Linux → Git → Docker → CI/CD → Cloud → IaC → Observability
  • Deploying and maintaining real infrastructure on a self-hosted Raspberry Pi 4B lab environment
  • Automating Android app delivery for FitForge via GitHub Actions → EAS Build → Google Play Store

Projects

Self-hosted music player running on a Raspberry Pi 4B. Demonstrates end-to-end Linux server administration: Nginx, Let's Encrypt TLS (DNS-01 challenge via Cloudflare), dynamic DNS automation via Cloudflare API, PWA support, and cron-based maintenance. Forked and extended with sequential playback mode and full localStorage persistence.

Currently in closed testing on the Google Play Store. CI/CD pipeline via GitHub Actions → EAS Build → Play Store internal track. Jest unit test suite. Lefthook + gitleaks for pre-commit secret scanning.

Background

Before pivoting to DevOps I spent 14+ years as a Digital Producer at Ironbark Marketing, spanning UI/UX design, front-end development, WordPress plugin development, and multimedia production. That background shapes how I approach infrastructure: documentation, system design, and the gap between what developers build and what operations teams maintain.
