Certi

An configurable URL shortener for Certificates (and other things).

It has a core library and multiple distributions: CLI Tool, Cloudflare Workers, and Deta Macro.

The URL of the Coursera certificate is too long, and putting it on the resume is breaking the layout, so I created this URL shortener.
