Animal shelters are non-governmental organizations that have to face many difficulties in their management and carry out actions to help unprotected animals in the area. Apart from being small organizations and generally having limited resources, many of them also struggle with outdated tools or face challenges in centralizing their information and processes. However, the main problematic faced by them is related to their economic situation and most of the times they need to use free online tools for their management. This work presents and explains a Phoenix web application solution to assist in the management of these groups, which leverages affordable development and easy maintenance with tailoring to meet their main needs. With this experience report, we aim to demonstrate that BEAM technologies, which have already proven their effectiveness in bigger corporations settings, such as WhatsApp or Discord, are also well-suited for smaller and more modest environments. Moreover, this aims to be an example of the use of Elixir/Phoenix in a non-profit environment, typical for social and community projects, with needs specific to the world in which they exist.
