Beyond the Code

A few things I enjoy when I step away from the keyboard.

I'm a huge coffee enthusiast. Whether it's a perfectly brewed espresso or a complex pour-over, I love the craft and culture behind a great cup of coffee.

You can often find me exploring with my phone, capturing moments. I have a passion for mobile photography and finding the beauty in everyday scenes.

When it's time to unwind, I enjoy diving into immersive worlds. Gaming is my go-to for a fun challenge and a great way to relax.
