I wouldn't call it unbalanced, though you may find being a true fiend a bit too much of a vulnerability with certain spells. Those spells may never come up but I have to ask, why not make this a tiefling variant? I think some DMs may not allow a fiend with no further consideration, but a lot more would be willing to take a look at a v- tiefling. If I were making a character with something like this in mind though, I think I would just use the existing tiefling, as it's so close.

is this race balanced or do you think it is unbalanced ?

This is pretty powerful. Take half elf, and remove fey ancestry, add weapon proficiency and fire resistance.
It's among the top tier races but not broken.
