At Charles Schwab, I develop and maintain Appium automation tests in Java for iOS and Android apps, covering core financial workflows and account features. I also investigate failures and improve automation stability in CI environments.

At PorchPass, I built a modular Playwright framework integrated into CI/CD and authored end-to-end and integration tests for loan workflows. I also partnered in sprint planning to define automated acceptance criteria.

At Zello, I led mobile automation strategy with Appium, creating regression and smoke suites for messaging features, including background services and offline messaging. Across my QA roles, I’ve built web and mobile automation frameworks and worked with teams to define acceptance criteria.
