Simple Queries and Functions on a Database
I can definitely see that Mohammed is skilled and experienced however I did experience issues with time management, transparency and the final product. The final product ended up including spelling mistakes in the code and many compiling errors even after being provided with a script to check correctness of the code. However, I think Mohammed is more skilled than this and is capable of much better than this.
