Interests

Outside of my work as a Infrastructure Lead, I thrive on a mix of active and tech-driven pursuits. You’ll often find me shooting hoops on the basketball court, whether it’s a pickup game with friends or practicing my jump shot. When the weather’s nice, I love hitting the outdoors for a hike or a casual run, soaking in the fresh air and scenery.

When I’m indoors, I’m usually glued to my computer, tinkering with open-source software projects or exploring the latest tech innovations in the technological world. I’m a huge fan of music—everything from indie rock to hip-hop—and I’m always curating new playlists. I also get lost in movies and TV series, especially gripping sci-fi epics, fantasy adventures, or binge-worthy dramas.
