Apart my interests in the IT sphere, I enjoy spending time outdoors. I am an avid rock climber and backpacker. I also enjoy putting together videos of my travels and events. Along with my amateur photography cinema-photography hobbies, it makes for a fun way to record and remember memories.

When Indoors, I'm a movie buff, an aspiring chef, and I spend a large amount of my free time exploring the latest technological advancements in cloud and web management fields as well as the design in the outdoor gear and equipment area. I’ve also recently begin putting together my own homelab that I use to test out various enterprise applications that can be used in a work environment.
