Troubleshooting slow DAX

I have the below code in RLS that is making my report extremely slow:

 

What am I doing wrong?

 

 

Role1:

Employee table:       

 

=[NT Username] = USERNAME()

 

 

Projects table:

 

=[Key_Project] IN

SELECTCOLUMNS(

    FILTER(

        'Engagement Role'

        ,'Engagement Role'[UserName] = USERNAME()

        )

    ,"Key_project"

    ,'Engagement Role'[Key_project])

 

 

 

Role2:

Employee table:

 

=[TeamLeadEmployeeID] IN

SELECTCOLUMNS(

                           FILTER(

                                                      'Employee Current'

                                                      ,'Employee Current'[NT UserName] = USERNAME()

                           )

                           ,"RLS_Ids"

                           ,[Employee Number])

 

 

 

Projects table:

 

= VAR MyEmployeeNumber=

SELECTCOLUMNS(

FILTER(

'Employee Current'

,'Employee Current'[NT Username]=USERNAME()

)

,"EmployeeNumber"

,'Employee Current'[Employee Number]

)





VAR My_Employees =

SELECTCOLUMNS(

    FILTER(

'Employee Current'

,'Employee Current'[TeamLeadEmployeeID] = MyEmployeeNumber

) ,"EmployeeNumber"

    ,'Employee Current'[Employee Number]

)





   



RETURN

[Key_project] IN

SELECTCOLUMNS(

    FILTER(

        'Engagement Role'

        ,'Engagement Role'[Employee Number] IN My_Employees

    )

    ,"Key_project"

    ,'Engagement Role'[Key_project]

)
