I take it you are looking for a transliteration (that is, the letters make sounds that sound like the name), rather than an actual translation.
There is no J sound in Hebrew. You will need to use a yod, which makes a Y sound. Hence, when read, it will sound like Yudeena? Still want to do this?
Hebrew is also read from right to left. So, with the following image, I will tell you which letters go where -
alef nun dalet yod
Understand that there is a nun for the start or middle of a word, and there is a final nun. I am spelling it with the regular nun.
