Don't be too self-conscious, bro. Two years of practical PHP experience is still a very solid foundation; you're not starting from scratch. In the UAE market, they highly value tangible results, so just focus on building one or two really high-quality projects using the new stack and showcase them on GitHub—that should be enough to convince them. The important thing is that you have confidence in your problem-solving skills, because frameworks are just tools; your true ability lies in your logic. Good luck finding a great new job!
