Experience

  • Visualizer of Diagrams of Electrical and Water Networks

    A C++ based application to display geographic and schematic diagrams of electrical and water networks.

    It consists of a standalone windows application that provides a powerful tool to manage large scale electrical or water networks.

  • Tool to Correlate Events of Electrical Networks

    A Javascript front-end (JointJS) to define behaviors using diagrams, integrated with a powerful big data component using Kafka and Apache Storm.

    The tool allows operators of electrical networks to determine what should occur under certain circumstances. It can generate alarms or trigger actions in the event of certain conditions met, as defined in the diagrams.

    Ultimately, it aims to provide a tool that reacts quickly and efficiently to situations of danger or low efficiency in the network.
