THE PERSON BEHIND THE PIXELS

An iOS developer.
A product-minded partner.

I’m Umer, an iOS developer based in Lahore. My work spans connected wellness, team communication, field research, entertainment, and on-demand services. I bring that range of product experience to every new challenge.

I work across the full application lifecycle: native UI, networking, local data, backend development, and App Store delivery. I care about readable, testable code, clear architecture, and details that make a product easier to use and maintain.
