Redesign of a Multi-market CMS Platform

One of my latest projects was a total redesign of a multi-market CMS platform for serving multi-language content across 17 markets. The platform was built on top of Adobe's Experience Manager with Knot.x serving as a layer of integration with various external services (Salesforce, Pardot, ExactTarget). The platform provided a standard set of components to enable quick delivery of new content which was then automatically translated using ClayTablet service integration. AngularJS was the solution of choice for large parts of the frontend, while Solr search engine provided search capabilities across various mini-applications throughout the platform.

As a QA Lead I was responsible for:
• Defining and implementing a quality assurance approach for the whole development lifecycle; this included the delivery process and development approach (e.g., Gitflow).
• Taking care of all quality-related aspects of the whole platform.
• Implementing test automation setup, development, and supervision.
• Designing and implementing the test infrastructure.
• Installing tools that support quality like SonarQube for static code analysis or monitoring dashboards based on the Smashing library.


An open-source, Java-based test automation framework with a wrapper for Selenium WebDriver. It utilizes Google's Guice to model websites as page object trees. It also integrates JUnit 5, Cucumber, Allure Reports, and AssertJ libraries and has dedicated modules for Adobe's Experience Manager test automation.
