Calda was hired to build a mobile application from scratch. The app provided users with a list of nearby locations that offer shelter during a natural disaster.

Calda successfully delivered a functional app. They did a great job of touching base regularly with the client and producing exactly what was needed. Better scheduling could've improved their efficiency, but the team still provided satisfactory work. The partners communicated via virtual meetings.
