Secure file sharing
Shieldited
Shieldited was designed for transmitting sensitive files at a time when encrypted transport was not consistently enabled across mail servers. It provided an account-free recipient workflow with email verification, a six-digit PIN, private link delivery, and physical file deletion after download.

The Challenge
Sensitive files were commonly sent as ordinary email attachments. Senders needed a way to deliver a confidential file without requiring the recipient to create an account and without leaving the file stored indefinitely.
The Approach
I conceived, designed, architected, and built the complete product. A sender uploaded a file and the recipient received a private link. The recipient entered their email address and then verified a six-digit PIN sent to that address. After the authenticated recipient downloaded the file, it was physically deleted from the system.
