Long story short

While a lot of the content here is about troubleshooting storage and virtualization tech, these days I'm diving into some seriously cool new stuff. Spoiler alert! GPUs, AI and even liquid cooling.

About me

Hi, I’m Juan Mulford, and this is my digital playground.

While some of the content here can get technical, this blog is not meant to be overly formal or overly serious. Technology should also be enjoyable, and I like to reflect that in both the writing and the style of the site, including some of the more playful featured images.

I have spent more than 15 years in the IT industry, working across a range of roles and technologies. I started in telecommunications and networking, and since 2012 much of my work has focused on storage, virtualization, and VMware-related technologies.

Over time, my interests have continued to evolve. Today, I spend much of my time exploring modern data center technologies, including GPUs, AI infrastructure, and advanced cooling solutions. It is an exciting space, and one that continues to reshape how we think about performance, scale, and innovation.

What began as a personal tech diary gradually became something more. I genuinely enjoy sharing experiences, lessons learned, and perspectives from the field. Through this blog, I document my journey across cloud technologies, infrastructure, and a variety of IT projects, with the hope that others will find the content both useful and interesting.

After spending a decade in Taiwan, I recently relocated to the United States. The location may have changed, but the curiosity and passion for technology remain the same.

Thanks for stopping by. I hope you find something here that informs, inspires, or simply makes the tech journey a little more enjoyable.
