Description

Paxel is a technology company that provides express delivery service for people in Indonesia. They have mobile application that allow user to send their package. After creating a shipment order, a courier will come to the user's location to pick up the package and deliver it to the destination.

As the company grows, they also made cooperations with various ecommerce platforms in Indonesia. Offering their delivery services to their sellers.

When I first joined the company. My first tasks was to maintain its v1 User App, which is built using React Native. At around mid 2020, I was tasked to develop the new version 2 of Paxel User App, on its iOS variant which is built using Swift and UIKit. Unfortunately, I can't see the finish of v2 User App, because I have resigned from the company before v2 app released.
