Work Experience
QA Tester Lead II
ADP, Inc. - Main
- Worked at ADP and built and maintained Appium-based automation for both Android and iOS using a shared Java framework that supported cross-platform execution while still handling OS-specific behaviors when needed.
- Implemented page objects and reusable flows for key journeys such as login and SSO, onboarding, timecard entry, PTO requests, and push-notification and deep-link validation, with environment-aware test data and stable locator strategies.
- Automated a “Clock In to break to Clock Out” scenario with dynamic waits, and validated that submitted entries correctly synced to the back end and reflected in the UI across devices. I integrated these suites into CI/CD with parallel runs.
Testing Automation Engineer
Overjet Inc.
- Created a testing framework from scratch with Java, Selenium, Cucumber, and Rest-Assured.
- Coordinated with a front-end engineer regarding adding HTML tags for testing usage so that the test framework would be much more resilient to the UI framework change from Angular to React.
- Worked with DevOps to integrate an automated testing suite into the CI/CD pipeline with Terraform.
Software Development Engineer in Test
Protocol First
- Created several frameworks such as Selenium, REST Assured, Cucumber, and Java.
- Built Java, Selenium, Appium, Espresso, XCUITest, and JUnit frameworks for mobile web and native app testing on Android and iOS devices.
- Set up the CI/CD pipeline with Jenkins, GitLab, and Slack API.
- Added a procedure that automatically took screenshots at every step—25000+ screenshots—and uploaded them to the AWS S3 bucket.
- Implemented an easy reading report with a free third-party plugin.
- Coordinated closely with the developers and related product managers to create test cases and troubleshoot discovered bugs.
Automation Engineer
ShoeSaleXpress LLC
- Developed an automated ordering system using Java, Cucumber, and Selenium to submit an order to different suppliers after the sale was made.
- Initiated the cross-platform listing tool with Java, Cucumber, and Selenium to expand product selling channel; maintained and updated codes periodically in case of supplier site changes.
- Created an automated Ruby script with gems like Nokogiri and CSV for the inventory, price, and description update.
- Integrated the automated email responding function combining Gmail, RubyXL, and .NET to automatically answer customers' ten most common questions.
Experience
Java, Cucumber, Selenium, and REST Assured Framework
The framework was designed to be easily used by manual testers, business people, and programmers. The idea was the following:
• The manual tester writes the test cases "visually," describing steps of what can be seen in the web and mobile apps.
• The programmer writes the automation scripts based on the visual test cases.
Overall, the speedup of the test cycle was 30% higher than the previous one.
Java, Cucumber, and Appium Testing Framework
The goal was to run a unified mobile web and desktop web testing codebase under the same Java class.
Automated Mobile Testing
I implemented Page Objects and reusable flows for key journeys, including login and SSO, onboarding, timecard entry, PTO requests, and push-notification and deep-link validation, with environment-aware test data and stable locator strategies (accessibility IDs when available; otherwise, resource-ID/XPath as a fallback). For example, I automated a “Clock In to break to Clock Out” scenario with dynamic waits, and validated that submitted entries correctly synced to the back end and reflected in the UI across devices. I integrated these suites into CI/CD with parallel runs on emulators and simulators and device farms, plus screenshots/log capture and failure triage to keep runs stable and actionable.
