Worked on the cowprotocol/cowswap repository to deliver Russian localization improvements for the frontend, focusing on refining translation logic and ensuring consistent UI text across key screens. Used React for front end development and applied both JavaScript and TypeScript to implement targeted updates that addressed translation inconsistencies. The changes enhanced accessibility and reduced confusion for Russian-speaking users by aligning translations with UI flows and strengthening localization quality assurance. This work involved a merged pull request that updated the application’s language support, resulting in a more coherent user experience for non-English audiences and demonstrating attention to detail in internationalization and user interface consistency.
