01. The Challenge
PayKite's legacy merchant portal was prone to frequent timeouts during peak banking hours, lacked granular team permissions, and suffered from an outdated, unintuitive user interface.

03. Step-by-Step Execution
- Designed 24 custom dashboard screens in Figma featuring interactive transaction charts and export filters.
- Implemented Role-Based Access Control (RBAC) with multi-factor authentication (MFA) and audit logs.
- Built real-time webhook streaming for instant settlement notifications and fraud alerts.
- Integrated automated reconciliation reports exporting to PDF, Excel, and CSV formats.
