I build interactive, real-time dashboards using React.js, Next.js, and Chart.js/Recharts, integrated with APIs or databases for dynamic data updates. For analytics-heavy projects, I use Power BI, Plotly Dash, or Matplotlib. Data pipelines are created using Pandas, SQL, and ETL scripts, with secure API endpoints to feed visualizations.
Dashboards are responsive, role-based (RBAC), and optimized for performance, supporting export to PDF/Excel.
