About Nuno

I’ve worked in infrastructure, automation and support for over 20 years — long before “DevOps” was a job title.

I solve problems by simplifying. By understanding the system, not just the tools. By removing friction instead of adding layers.

I write this blog to document what I’ve learned, what I’m building, and what I believe still matters in tech.

Professional background

  • 20+ years working across support, security, systems, and reliability
  • Early background in electronics and distributed systems
  • 10 years in the Point of Sale (POS) industry: kernel patches, driver tuning, cross-distro installs, receipt printer integration
  • Built CI/CD pipelines for microcontrollers, e-commerce stacks, infrastructure as code, and homelab automation
  • Created solutions using Ansible, Docker, Sceptre, AWS, password-store, GPG, SSH certificates, and runit (among many others)
  • Projects range from single-server setups to distributed VPN-managed environments
  • Experience with both highly regulated corporate settings and experimental home labs

What I value

  • Clarity over complexity
  • Documentation that actually works
  • Security by design, not by patch
  • Tools that respect the user’s time
  • Systems that fail with grace

I don’t chase hype. I improve what I already use. I prefer quiet systems, strong defaults, and logs that make sense.

This blog

pulsingminds is where I publish practical solutions, reflect on patterns I’ve seen in infrastructure, and sometimes share the personal stories behind what I build.

It’s not a tech demo. It’s not a portfolio. It’s a notebook — written loud enough to be useful to others.

If you're here, you probably build things too. Welcome.
