hi guys sorry if this is not a pure code question but honestly there is no better people to ask than here i am a double major pure math and computer science in egypt and i graduate in exactly 4 months , im targeting core systems like crypto and ai infrastructure companies i finished c and cpp but completely lack big projects and design patterns , my plan now is to read OSTEP and CS:APP and some courses for high performance computing and CUDA . i plan to make maybe 3 medium projects and 2 somewhat big ones . i wanted to learn rust too but clearly no time i need a job first then later i will focus on rust and distributed systems im really freaking out about a few things , first the volume of these books and projects is huge for 4 months . second is the job market because system level and OSS jobs are literally zero in my country so i must aim for remote jobs . but is remote really possible for junior systems or do companies strictly want on site . because getting a work visa right now is almost impossible with the global situation also my english is quite weak maybe B1 and im scared it will ruin my chances please guys i dont want just general random advice i really prefer opinions from people who went through a similar path or know the market . sorry again for the non tech post but im really lost and need a reality check . thanks
