The challenge

Sell digital e-books securely, without handling every order by hand.

The solution

Every PDF is watermarked, customers sign in with a one-time code sent by email and get their own account area. Files are stored through the S3 API.

The partnership

A freelance engagement taken from design through launch to ongoing maintenance and new features.
