Can you use the expression as a result at the end?

Yes, you can use the expression "as a result" at the end of a sentence, but it's less common. Typically, it's used to introduce the consequence of a preceding statement. For clarity and flow, it’s often more effective to place it at the beginning or in the middle of a sentence. However, if the context is clear, ending a sentence with "as a result" can still be grammatically correct.
