Experience
Mobile Automation Framework – Sauce Labs App (UIAutomator2 & WebdriverIO)
https://github.com/mofeezamasood/Appium-Webdriverio-UIautomator-CucumberAppium iOS Automation Framework (XCUITest & WebdriverIO)
https://github.com/mofeezamasood/Appium-Webdriverio-XCUI-CucumberI designed and implemented end-to-end automated test scenarios covering critical user journeys, including app launch validation, UI interactions, form inputs, navigation flows, and element synchronization. The framework follows clean automation principles with reusable utilities, clear separation of test logic, and robust locator strategies to minimize flakiness. I addressed iOS-specific challenges such as system alerts, permission handling, and dynamic UI elements to ensure stable execution.
I am extending the framework to support Flutter-based applications, exploring Flutter-specific locators and automation strategies. I leveraged GitHub Copilot and Claude Code to accelerate setup, refine locators, generate edge-case scenarios, and troubleshoot synchronization and visibility issues.
