DataSite Testing Evolution & CI/CD Implementation

Led the strategic transition from Selenium to Cypress, leveraging JavaScript's power for enhanced testing.

I architected a robust test framework that dramatically improved reliability and efficiency. I also introduced and managed the CI/CD pipeline using GitHub Actions to automate and streamline the software delivery process.

The new framework drastically minimized test flakiness by over 95%, reducing test execution time from 3 hours to under 30 minutes. Simultaneously, the CI/CD integration ensured timely, consistent, quality releases, reinforcing DataSite's commitment to excellence.

CNBC Mobile Application Quality Enhancement & Framework Transition

Spearheaded a comprehensive quality enhancement initiative for the core and compacted applications spanning multiple platforms, including web, iOS, Android, and OTT devices.

My team and I delved deep into automating test suites for Android and iOS platforms, focusing on ensuring impeccable user experience and performance, all while maintaining crucial release timelines. Recognizing the limitations of the existing Calabash test framework, I championed its migration to a more contemporary and scalable Appium with Cucumber setup for mobile automation. This strategic transition aligned with best testing practices and principles and fortified our team's performance.

Our relentless pursuit of excellence bore fruit, evidenced by a stark reduction in production bugs and customer complaints. As a direct result of these efforts, the application ratings soared from 3.2 to 4.3 stars on the Play Store and 4.1 to 4.8 stars on the App Store, cementing CNBC's position as a frontrunner in mobile application quality.

Vanguard's Automation Coverage Revamp & Process Optimization

Overhauled the existing manual testing approach for the internal application spanning mobile and web platforms—a significant responsibility entrusted to me by Vanguard.

Recognizing the need for greater efficiency and accuracy, I and a skilled team initiated a series of strategic changes. The prime focus was the introduction of in-sprint automation, ensuring that each new feature was concurrently met with its corresponding automated test. With a firm belief in continuous improvement, I worked collaboratively with product managers and teammates, refining and enhancing test strategies based on feedback, subsequently increasing the test coverage. Furthermore, our joint efforts also centered around defining processes and meticulously authoring and refining test cases.

The revamped automation strategy mitigated the release process's complexities and substantially increased the test coverage—from about 20% to over 80% of all test cases—marking a pivotal moment in Vanguard's journey toward QA excellence.
