Overview
Most people open a PDF on their phone to do one quick thing: sign it, fill in a form, mark something up and send it back. The app has to make that fast, and it has to work well with Apple Pencil on iPad.

Designed and implemented a PDF creation and editing app with annotations, fillable forms, and collaboration features using PDFKit and PencilKit. Enabled users to create, annotate, and share PDFs with a focus on productivity and ease of use.
