The QR code that belongs on a developer CV
Recruiters print CVs. Interviewers read them on a train. A GitHub link that has to be typed out by hand is a link that never gets opened — and "github.com/firstname-lastname-dev" is exactly the kind of string that gets mistyped. A small code in the header solves it in one scan.
Monochrome suits GitHub better than colour: the classic black-on-white preset prints cleanly on a CV, photocopies without losing contrast, and matches the platform's own visual language. Keep the code to about 2cm square in a document header.
Conference badges and laptop stickers are the other natural homes for it. Both are read at close range by people who already have a phone in hand, and both outlast whatever URL shortener you might have used instead — the link is baked into the pattern, not rented from a service.
Everything happens in your browser. The QR encoder is built into this page, so your username is never sent to a server, nothing is logged, and there's no daily limit. The code is static — the link lives in the pattern itself, with no redirect service in the middle that can expire, start charging or go down.
