Introduction. In Ecuador, there are currently many problems in the penitentiary system, which has led to the lack of technological means to deal with this problem finally. On the other hand, the latest statistics show a deficit in the security of the penitentiary centers in Ecuador, which further aggravates this demanding situation, since the controls for the entry of people are conducted manually. An agent keeps a record of all visits on paper sheets and on rare occasions makes use of spreadsheets. Likewise, the register of inmates in each of the prisons is kept manually, which causes a series of inconveniences such as: not having the exact number of inmates in each of the prisons, not having an orderly categorization, and information is only available in printed media, outdated information, no statistical reports. On the other hand, the use of technological means, as well as real-time communication, have become more important in this digital era. For this reason, the development and use of web applications, mobile applications, desktop applications, and progressive web applications, among others, have allowed automating tasks and better control of information in small, medium, and large companies. Objective. To develop a backend for the management of Ecuador's penitentiary system. Methodology. The method applied was deductive with a qualitative approach, with an experimental and documented design. Results. Among the results obtained in the research and the application of the technological tools, it has been possible to develop a backend that allows them to manage the personnel working in the prisons, such as directors, guards, and prisoners. In addition, to obtain information in real-time about the wards, and prisons and to make reports by the guards. Conclusion. It is concluded that the use of current development tools that are scalable over time, as well as the implementation of an appropriate development methodology, has allowed the development of a technological tool that allows the maximum authorities of the penitentiary system to obtain detailed, efficient, organized information in real-time thanks to the use of technology.
