BangladeshWhat I'm looking for
At Karaz Platform, I lead four designers across six product modules and own a 500+ component design system used directly by a 16-person engineering organization. I shipped five role-based dashboards and designed an AI and IoT diabetes companion now in 500+ Saudi clinics.
At Niyyah, I improved retention, activation, and paywall conversion through user research and product iterations. Through my independent practice at Lumixel Studio, I’ve delivered client engagements across SaaS, fintech, healthtech, and consumer mobile, including a fintech redesign that cut support tickets by roughly 40%.
