I think you mean اشوفك بعدين, right? اشوفك بعدين is colloquial أراك لاحقاً is standard Arabic Both mean "see you later" Hope this helps.

اشوفك بعدين not بعد اراك لاحقا it's the same meaning see u later

أشوفك بعد: see you after And it's not standard Arabic. But you can use it like this: See you after the exam أشوفك بعد الامتحان And this is how we read it: ashofak ba'ad أراك لاحقا: see you soon And it's standard Arabic, You can use it like this: I'm leaving now, see you soon. أنا مغادر الان، أراك لاحقا And this is how we read it: arak lahiqun
