Mawj is a social audio app — voice rooms people drop into to talk, in the style of Yalla or Clubhouse. Beyond the core room experience (explore, speak, listen, manage a profile), it grew a full virtual-economy layer: a CP (points) system, purchasable recharge packages, custom room backgrounds, and a medals system for active users.

It's the largest Flutter codebase in my project list — each major feature (CP system, medals, recharge, custom backgrounds) has its own internal design doc, which is how a solo-built app stays maintainable as it grows past a couple hundred files.

Actively iterated — the CP, medals, recharge, and custom-background systems were each added as follow-on features after the core room experience shipped.
