Building Mozark App Studio

May 2026 – Present · Product Engineer · appx.mozark.ai/no-code-studio

App Studio is a no-code platform that lets anyone create mobile test cases in plain English and run them on real devices, without writing automation code.

Scripted test suites break every time the UI changes, and keeping them green eats whole teams. App Studio flips that: describe what the user does, and agents turn it into a test that runs, and repairs itself, on real Android and iOS devices.
