Worked on the MONETA-SmartBanka/localization-json repository, focusing on enhancing payment safety messaging and improving UI localization consistency. Delivered two features: an active call scam warning integrated into payment flows, which informs users of potential phone scams and offers cancellation options, and a refinement of localization naming by renaming slideButton to primarySlideButton in both English and Czech locales for greater UI clarity. The work emphasized traceable, well-documented commits and addressed business needs without introducing new bugs. Utilized front end development skills and applied internationalization and localization best practices, primarily working with JSON to ensure accurate and consistent user interface translations across locales.
