This Shiny app helped internal operators anticipate issues on the electricity grid and decide whether they should send someone before more serious issues could appear.
The client hired me to improve the already existing app and make it look professional by speeding it up, improving the design with the help of a designer, and adding many new data visualizations involving maps, timelines, custom tables, and multi-screen forms.
