When I'm not coding, I'm often exploring the pixelated world of Minecraft.
🪓 Whether it's building massive redstone contraptions or surviving hardcore mode, I love the creativity and challenge Minecraft offers.
Sometimes I even experiment with Minecraft modding and server management for fun.
Favorite biome? Definitely the mountains 🏔
Dream build? A fully automated city with redstone tech and command block magic ⚙️✨
