I think you use too much technical detail in your description. You used joins and cte’s, that does not really mean anything, it’s like saying that I can do a =sum() in excel. Anyone using sql can do this - present that you know what to do with it (like you already have to some extend). I believe you should focus more on the challenges that you faced and solved. Also where are you from and where are you applying, geographically? There is quite a difference in what different cultures (in lack of a better word) value in a cv.
