Who is Alex?
Programmer
Gamer
Metal & Rock
Hello! I'm Alexis, but I prefer to be called Alex. I'm a programmer, and in my free time, I also enjoy going to the gym, watching series and anime. My favorite series is Dr. House, and my favorite anime is One Piece. Additionally, I love music: I listen to almost any genre, but among my favorites are rock and metal, with artists like Avenged Sevenfold and Taylor Swift. I also play Minecraft, PUBG Mobile, Pokémon Unite, Crash Bandicoot, and Resident Evil 4 Remake, and I hang out with my friends.
