Was he? Not my understanding. The gospels show him doing a lot of things he would simply not have done as an observant Jew. He [rightly] told his disciples not to preach to gentiles or Samaritans. His tiny sect was Jewish until Saul stuck his oar in, ignoring Jesus’ instructions.
Matthew 10:5 “These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:”
(KJV)
Matthew 5:17 :“Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. (KJV)”
Paul simply abolished the ritual commandments, such as circumcision and dietary law and allowed gentiles to become followers of “The way”. I’ve said it before and I’ll say it again, Paul was a deluded loon who founded a religion on his hallucinations and delusions. Possibly an epileptic.

A couple of other examples: The woman taken in adultery had committed a capital crime under Mosaic law and was being executed as prescribed, by stoning. Jesus would have known that and would have been aware that if he interfered he might have been stoned. If he had forgive the woman, he would have almost certainly been stoned for blasphemy.
No observant Jew would declare himself god or the son of god. He would be stoned for blasphemy, probably by some of his own disciples, if not all.

I recommend this brief clip with Bart Ehrman on how jesus became god. There are a couple of full lectures on Youtube on the topic.
Just to start: In his life time, Jesus did not call himself god. He was called god in the book of Mark, but not in Matthew or Luke, and most importantly in Mark the earliest gospel from which all the others copied… Nor did Paul refer to jesus as god according to Ehrman.
