Omar Rizwan

Hello! I'm Omar. I've been interested in new computer interfaces and new ways of programming (aren't these the same thing?). I've worked at Dynamicland (check out ⭐ Geokit!), at Stripe, and at Khan Academy.

I'm the creator of ⭐️Screenotate, a tool for macOS and Windows which captures the text and origin whenever you take a screenshot.

Get in touch if you want to talk or work together—
