PROFILE

Umay Şahan

Worked on CrocSwap’s perps-app and ambient-ts-app, delivering robust UI features and data reliability improvements for trading workflows. Built unified, sortable data tables and real-time ledger updates using React, TypeScript, and WebSockets, enabling dynamic financial data display and persistent user preferences via localStorage and Zustand. Enhanced data export with precise formatting for Excel and CSV, improved localization, and implemented robust sorting logic across order and trade history. Addressed edge cases in dropdowns and pagination, cleaned up code for maintainability, and standardized state management. The work strengthened data integrity, reduced latency, and established a scalable foundation for future analytics and reporting.
