Abstract Expotecnología is an event aimed at students, teachers and professionals in the areas of systems, computing, petrochemicals, process control and industrial instrumentation, electronics and telecommunications, electricity, electromechanics and civil works, with the purpose of addressing not only the challenges that accompany the various activities in which related professionals perform, but also the problems, projects and programs of the academic units in which they are trained. In addition, it is a conducive space to enhance their role in the profession, research and academy. Currently, there is a website for the Expotecnología event, which can be seen here: https://expotecnologia.unitecnar.edu.co. But all the scheduling and schedule management is consulted manually by means of flyers, billboards or email. In this sense, it is necessary to develop a progressive web application, where all the optimized processes can be carried out, in addition the participants to the event would not have any inconvenience to know the day, time and place where they will be presented, because it can also work without internet connection (offline).
