  • WordPress Plugin for PDF Document Management

    I created a plugin allowing special district clients to manage PDF documents independently from the WordPress media library.

  • Electoral Divisions Redistricting Map

    I was responsible for producing an interactive map identifying 2021 Electoral Divisions for a local sanitary district.
