About
Back in 2010, I decided to try my hand at building my first computer and tumbled headfirst into the rabbit hole of the software and hardware world. Fast-forward to today, I am working at Amazon Warehouse Services, where I can troubleshoot, fix, and deploy new technology for hundreds of thousands of customers around the world. My main focus right now is to build the best network fabric and keep hardware and software up and running as smoothly as possible to minimize any downtime for our customers.
In my free time, I tend to immerse myself in today's cybersecurity threats and new technologies emerging from every corner of the internet. I avidly read research papers and engage in online forums to gain insights from experts and fellow enthusiasts. Understanding the intricate techniques employed by hackers and malicious actors fuels my motivation to fortify our systems and protect our customers' valuable data.
When I'm not at the computer, I'm usually riding motorcycles, hanging out with my wife and dog, or trying to find the best tacos around Los Angeles.
