写完 is 写 + 完:
- 写 = to write
- 完 = to finish, complete
So 写完报告 means finish writing the report.
Here 完 is a result complement, showing that the action reaches completion.
Chinese often does not need 了 when the completion is already clear from a result complement like 完, especially in a time phrase such as 写完报告以后.
So this sentence sounds natural as written.
You could also say 写完了报告以后, but it is a little heavier and not necessary here.
以后 means after or afterwards.
In 写完报告以后, it connects the first action to the next part of the sentence:
- 写完报告以后 = after finishing the report
It creates a time clause. A very natural English equivalent is After you finish writing the report...
