What makes you Premium Power BI Developer?

There is huge crowd of Power BI Developers because the learning curve of Power BI at visualisation level is very easy and not takes time as it has self explanatory drag & drop features.

Another reason to have large number of Power BI developer availability is that most of the people are familiar with basic excel and Power BI inherit the design approach from Excel therefore it enables non technology person to learn Power BI quickly.

But there are key areas where one can be Power BI premium developer and stand out in the crowd.

SQL/PL-SQL - Many will be debate that SQL/PL-SQL level is not required to build Power BI dashboard. But most of the legacy and large enterprise solutions are running on databases. Therefore, large project always has SQL database as source. Therefore you need to fair to advance level of sql knowledge to reduce the modelling & DAX complexities. SQL enables a Premium developer to understand the data source effectively and design the more coherent data models.

Data Modelling - One of the core part of building effective Power BI solution is Data modelling. Most of the developers start with excel as data source to start the learning. But real enterprise data sources are way more complex. Therefore understanding of the data modelling is considered key skills. Bad data model always leads complexities and poor performance of the report and increase the development time.

Effective Design - PowerBI dashboards serves to the executives and it is vital to have a very effective design at first place that resounds the branding of the company and at the same time enables CXO's to view the dashboard with minimum efforts and few clicks. Having fancy color, font and image is not part of the effective design. It is more than it.

Advance DAX - Advance DAX is considered the pro skill of a Power BI developer. In real time business scenarios calculations are not straight forward as they seems during learning phase. There are always many business logics and variables are included in calculations which can not be served by data model alone. Therefore Practicing the advance DAX can transform an ordinary Power BI developer to Premium Power BI Developer.

Performance Tuning - One of the pain point of any technology solution is performance tuning and Power BI is not alone which is untouched by this phenomena. When we deal with heterogeneous data source in Import or direct query mode or sometimes mixed of them, it is crucial how effectively we design the DAX and visuals. Power BI takes time to process the data and then render on visual. This trip of showing visual on Power BI will lead to poor performance if data processing will take time and end up showing an error on visual. So knowing the performance tuning of the Power BI will finally push you toward the greatness of Premium Power BI developer.What is your thought? please share.
