Built an interactive drag-and-drop IVR Flow Builder UI using ReactFlow, including 9 custom node types, real-time canvas preview, and a visual conditional routing interface for non-technical operators. Developed an IVR Analytics Portal with 20+ KPI cards and Recharts dashboards (call volume trends, peak hour heatmaps, drop rate charts), plus a virtualized MUI DataGrid designed for high-volume data operations (100k rows) with filtering, sorting, and CSV export. Partnered with the backend team on API contracts and data-flow decisions during sprint planning and code reviews.

Developed responsive, accessible UI for a B2B SaaS travel platform using Ant Design, creating four role-specific panels (SuperAdmin, CompanyAdmin, AgencyAdmin, AgentPanel) with performance and cross-browser compatibility in mind. Worked with backend and product teams to integrate REST APIs and implement state management with Vuex, while maintaining consistent design standards across the application lifecycle.
