• Develop and maintain BI dashboards and regular analytical reports using Apache Superset, and occasionally Power BI, Tableau
• Create report prototypes and analytical visualizations independently when needed
• Contribute to the automation, standardization, and optimization of reporting processes
• Conduct demo sessions for stakeholders and prepare user documentation to facilitate adoption of delivered solutions
