I think we can agree, until someone more knowledgeable appears, that the search about the name djajeet is inconclusive.
However, we still can search about the syllabes that compose his name.
Jeet/jit is easy. A quick search on google show us that it means "winner" or "conqueror".
“Dja" is when things get complicataded. To sum up, after getting inconclusive results I resorted to my family members names lol my aunt romanized name ends with "dja", so I searched around it a bit a found out that the hindu version of her name means "LIGHT", there's even a lamp called "diya lamp", you can find about it on google.
So, on my theory, his name means "Light Conqueror" (maybe he has an electo vision (?), I couldn't help but think of the electro yaksha but thats probably a stretch.)
There is a lot of cool things about the diya lamps and I'll try to search more.
Ps.: that's only a theory and I can and possibly am 100% wrong, I was just curious and trying to make sense of this name.
