[chanalku91]

If your usual life-style was of a nocturnal type, ie you're of a nocturnal-type of guy or  you have a night-long job or something similar, then yes!.. No problem with that, I guess. But, if shifting your entire life-cycle was done specifically to avoid the hardship of fastning, then I'm afraid that's not what the Ramadan month stands for, and you're missing a lot of its blessings....

I'm not judging you there @chanalku91!.. But I had to make that remark -between brothers- after having read your response :-)

has become a habit of working at night!

I choose work at night, so I stay focused while working!
too much noise during the day!

and, because in the month of Ramadan there are already many thief in action!
so, this becomes an additional task, guarding the house from thieves!
