Jesus is yeshua so he is the saviour.

Yeshua means YAHWEH saves.
In Hebrew the name is Yeshua. This is a name that is composed of two words, Yahweh Shu‘, meaning saviour.

Jesus is not the only name Yeshua in the Bible... 

The name Yeshu’a, or Yeshua, which is Jesus’s proper Hebrew name, was a common name in the period around the first centuries. There are several other known people from these times who were named Yeshua, and fellow worker of Paul. He was also called Jesus. (Col 4:11).  And  "At that time they had a well-known prisoner whose name was Jesus Barabbas. So when the crowd had gathered, Pilate asked them, “Which one do you want me to release to you: Jesus Barabbas, or Jesus who is called the Messiah?” Matthew 27:16 - 17 NIV
