Hi, my name is Daniel and I started my adventure with computers from computer games. At first, like the rest of the boys from the neighborhood, we would go to the games club in the garage on the next street and play the slot machines. Later, it was time for computers, Windows reinstals, virus removal, component tweaking, and completing projects in college.
Privately, husband and father who like to ride a bike and go hiking in the mountains and play online FPS games in my free time.
