Worked on the defuse-protocol/defuse-frontend repository, delivering targeted improvements to both user experience and data reliability. Addressed a bug in the history feature by refining how derived addresses are handled, ensuring that address displays accurately reflect verification status and wallet state. Introduced a real-time balance refresh mechanism after swaps, leveraging state management and query invalidation patterns to keep account balances up to date. These enhancements, implemented using React and TypeScript, reduced user confusion and support overhead by providing more accurate and trustworthy information. The work demonstrated a focus on frontend stability, collaborative development, and practical application of modern frontend techniques.
