The challenge was twofold: to develop a comprehensive application that would not only allow Gestión Post to manage its shipments efficiently, but also offer end users the ability to create shipments on their own. To meet this challenge, the team, composed of a Project Manager and two developers, set about the task of simultaneously developing the APP, the API and BACKOFFICE. The strategy was clear: quickly implement a version that would optimize the client's day-to-day operations, and then focus on maintenance and implementing continuous improvements based on the client's specific requirements.
