Beyond engineering, I'm an avid gamer who enjoys 100%-ing difficult games. I'm a big fan of the Resident Evil franchise and enjoy games like Hollow Knight: Silksong, Cuphead, and Ghost of Tsushima.
I also love watching movies, with the Dune and Spider-Verse franchises being two of my favorites, and am always down to see the latest releases.
