How are you currently developing yourself? What have you learned in the last six months to a year?

To improve in BI and visualization tools, I regularly study new features of Tableau and Power BI, and also practice on real data.

Over the past six months, I have learned:

• Advanced DAX functions in Power BI for creating complex calculations and metrics.
• Using Tableau Prep for data preparation and cleaning.
• Integration of Power BI with various data sources, including APIs and databases.
• Basics of dashboard performance optimization.
• Practical cases of business metric visualization and building interactive reports.

I also follow relevant communities and take online courses to stay updated on new trends and best practices.
