Worked on stabilizing the UI fee display for the sushi-labs/sushiswap repository, focusing on maintaining accurate fee presentation rather than introducing new features. Addressed a regression by reverting a previous UI fee fix, ensuring that users continued to see correct fee information and preserving trust in the product. Utilized TypeScript and front end development skills to validate the stability of the UI across affected user flows, preventing potential misrepresentation of fees. Documented the regression and the rationale for the reversion to support future audits and knowledge transfer, prioritizing risk reduction and minimizing support issues related to fee display inconsistencies.
