On weekends, I love hitting hiking across Ireland with my camera, snapping photos of amazing landscapes and cool moments. I'm also a bit of a DIY enthusiast - there's really satisfying about fixing or building things with my own hands!
Traveling is another big passion of mine - I love exploring new places and experiencing different cultures.
