jaffar keikei is passionate about building secure and scalable solutions

"it isn't that we dream too wild a dream: the trouble is we do not make it seem sufficiently unlikely; for the most we can think up is a domestic ghost." — Vladimir Nabokov, Pale Fire

I build systems that live at the intersection of technology, art, and philosophy. My work reflects a love of exploration, questioning boundaries, and a belief that limitations are just unasked questions.
