Transforming Digital Quality: Insights of a multinational QA leader
Among the contemporary digital goods, the expectations of a user in regard to the smooth, responsive, visually consistent experiences have never been greater. When consumers are streaming music, talking to their intelligent devices or even being the recipients of specifically targeted digital advertisements, it is an unseen field of engineering that is making the difference in terms of how the customers are interacting with technology. The driver of this intelligent and AI-empowered post in testing is none other than Jessy Christadoss, a Senior Quality Engineer with more than 15 years experience in India, Singapore and the United States.
She has changed the quality engineering field to be a prospective, AI-led field that is no longer at the end of the software lifecycle, but an integrated and imperative design-time need. The expanse of her career, which took her through the content systems of enterprises in India, the mobile advertising systems of Singapore, the end- to end test leadership of the streaming and ad-tech firms in the U.S., exemplifies how knowledge of the global expertise is one that can help in enhancing the quality of software and at scale.
Transcontinental Experience and Breadth
Jessy started her QA career in India working with the major technology companies designing documentation and automation practices with big enterprise customers. Her transfer to Singapore to work in the mobile and data platform was presage to a business directing test programs in advertising analytics and societal social apps on mobile. She had worked in several different time zones and cultural expectations at companies located in Singapore and then Texas and developed instruments of testing fit to maintain platforms with concurrence and realtime reviewing.
Each country, each product category was a learning experience to Jessy. I got the experience of validating the performance of programmatic advertising in real-time in Singapore. In America, My areas of concentration were on multi-device consistency, visual validation and ensuring AI works in the QA.
Her testing expertise includes a wide span of platforms—ranging from Android Automotive OS and smart TVs to iOS/Android mobile applications and web. Her work has covered advertising exchanges, medical device portals, and infotainment systems. As a result, she brings a nuanced understanding of how user expectations shift by geography, platform, and product intent.
Scaling Quality in a Subscription Media Ecosystem
Jessy’s most enduring impact came during a seven-year tenure at a major subscription-based media technology provider in the United States, which offers audio entertainment through both satellite and digital streaming. Starting as a mobile QA tester, she grew into the role of Senior Manager of Quality Engineering, where she led a 25-member QA team spanning manual, automation, and third-party resources.
Her mandate included mobile, web, TV, and automotive clients across multiple branded properties. Her QA team identified over 2,200 defects during a single release cycle—79% of which were blockers or critical issues. “The scale of QA wasn’t just about defect volume,” she said. “It was about precision. We were optimizing for five platforms simultaneously.”
Notably, she led the integration of AI-driven defect prediction models and test prioritization algorithms, which improved defect detection rates by 25%. She also championed AI-powered visual regression testing using Applitools Eyes, a solution that enabled automated, pixel-perfect UI validations across web and mobile platforms. These initiatives led to a 30% drop in visual defects and helped establish confidence in cross-device compatibility and user interface consistency.
Jessy embedded these AI checkpoints into CI/CD workflows via GitHub Actions and Jenkins, ensuring that regressions were caught before release. The team also integrated Applitools Eyes with Selenium, Playwright, and Appium, enabling a proactive approach to visual consistency for React Native apps and responsive websites. This fusion of AI with traditional automation frameworks reduced triage time for visual regressions by over 50% and accelerated product delivery cycles.
