As a contractor, worked with my client's mostly new-to-Elixir development team to build software that pulls hundreds of millions of rows of data from internal and external APIs, calculates some carbon emissions data, and displays it in a web UI.
Demonstrated and explained various Elixir patterns to the client's employees.
Built multiple GenServers that ran in a small Erlang cluster and periodically fetched large amounts of data.
Built a LiveView UI to view the supervision tree and enable/disable individual GenServers in real time.
Built parts of the application UI, which was mostly about searching for data, viewing data, and downloading data.
