  • Delivery Helper Mobile App | Onion Go

    A native Android app that allowed food delivery workers to claim orders and deliver them to customers. It was linked to Onion Menu, a food delivery app that allowed customers to make orders in restaurants.

    Once a restaurant accepts an order, Onion Go notifies the delivery workers about the new order that's being prepared, so they can claim it and deliver it. The app separates orders in cards with the restaurant's address, the given customer, and the amount of time the order will take until it's ready to be picked. When changing the order status in Onion Go, the status is reflected on Onion Menu, so users can track where their food is.

  • Android App for Pressure Ulcers Prevention

    An Android app used by nurses in hospitals to track and prevent pressure ulcers on patients.

    By filling a form in the app about the status of a given patient, it provides the necessary actions to be taken to prevent or treat pressure ulcers the patient may or have developed.
