Project overview
Modernizing a legacy courier app (Courier 1.0 to 2.0) to improve its performance, usability, and scalability without disrupting the daily operations of over 10,000 couriers nationwide. The project involved rewriting the code of the old app and implementing a gradual rollout of new features. Our team also focused on adding new business functionalities, enhancing the system’s stability, and upgrading outdated terminals.
Client background
A leading courier and parcel delivery company that is part of a large international network in Europe. Our client boasts an extensive network of courier and pick-up and drop-off (PUDO) points, including parcel lockers.
Goals
Updating a legacy app couriers use to ensure it delivers improved performance and usability, while allowing for increased parcel volume and profit growth. Enhancing courier performance by reducing in-app processing time and minimizing error rates. Facilitating easy and quick courier app integration with the expanding out-of-home (OOH) network, leading to a wide range of new product lines and monetization opportunities. Eliminating legacy code and updating the tech stack to ensure faster time-to-market and better scalability. Incorporating new, up-to-date features such as support for parcel machines, PIN on glass payments, and enhanced barcode scanning to improve overall app usability. Replacing outdated Zebra terminals and upgrading the tech stack with the latest releases.
