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.
Every GitHub code made here is static: the link lives in the pattern itself, with no redirect service in the middle that can expire, start charging or go down. There's no account, no watermark and no scan limit — download it once and it keeps working for as long as the GitHub link behind it does.
