  In Zé i was part of the team that develop the app used by the delivery person when it started to turn into a independent app for couriers to use, instead of just a tool.

Unfortunately this new project had to stop because the pandemic started. So, with new demands knocking our door, i moved for the Payments team where we implemented the first version of online payment for our deliveries.
