Worked on the Backbase/golden-sample-app repository, developing end-to-end test feature files to validate transaction workflows, including details view, list view, and search functionality. Applied Behavior-Driven Development principles and Gherkin language to define scenarios that check transaction details, formatting rules, data consistency, and search/display accuracy. Focused on strengthening automated test coverage, enabling the QA team to identify issues with user experience and data integrity earlier in the release cycle. Leveraged test automation patterns and maintained Git traceability for all changes, supporting spec-driven development and collaboration. This work contributed to faster QA cycles and more reliable releases without addressing bug fixes.
