[name] asked: tell an interesting case from your last job

At my last job, I participated in a project to optimize reporting in Power BI for the sales department. The main goal was to speed up the loading of large dashboards and improve their interactivity.

To achieve this, we:

• Rewrote complex DAX calculations, breaking them into simpler measures.
• Implemented aggregations at the data source level to reduce the volume of data processed.
• Used parameters and filters for dynamic data loading.

As a result, report loading times were reduced by 3 times, and users received a more convenient and faster tool for analysis.
