Software engineer & founder of Fast QR

Rehan Haider is a software engineer and the founder of Fast QR. He's spent over a decade shipping production web systems and now builds tools where privacy is the default — not an upsell. The free generator runs entirely in your browser, so the data you encode never touches a server. Richer tools for teams are on the way.

Rehan started Fast QR because too many QR generators came with strings — an account, an email, a tracking pixel, or a watermarked PNG. Fast QR is what the entry point should look like: in your browser, no signup, no tracking pixels.
