Umay Sahan developed and enhanced data-driven user interfaces for the CrocSwap/perps-app and CrocSwap/ambient-ts-app repositories, focusing on real-time financial data visibility and robust user workflows. Leveraging React, TypeScript, and WebSockets, Umay implemented unified, sortable tables for positions and history, persistent state management with Zustand and localStorage, and real-time ledger updates to reduce latency in user-facing data. The work included targeted bug fixes for sorting and edge-case UI reliability, as well as localization improvements and codebase cleanup. These contributions improved data accuracy, reporting, and maintainability, demonstrating a strong grasp of frontend architecture and scalable state management patterns.
