Here in the US, we prefer focusing on one specialization. Pick one and master it because the web development here is super dynamic. UX/UI is one person, 1 for front end, 1 for back end, 1 for DevOps. No one can handle such a big dynamic and interactive website alone here. And if you claim that you're a full stack expert at a younger age then they assume you start coding since high school or you lie on your resume. I encourage everyone to focus on one specialization, especially the backend and database. And those who are strong in math and analytical skills, then go to Computational Math, Data Science and AI. Those who are creative and bear the headache of algorithms, then go to app development. Some people say "achitect's dream is engineer's nightmare". In app or web development, UX/UI's dream is a programmer's nightmare 😂😂😂 In Cambodia, we need more Information Technology expert (not IT that we always say, this is IT who is an expert in the network, virtual environment), and Cyber security expert.
I don't know. I never tried. If you can and you have time to code your backend or using BaaS ( Backend as a service), no one can stop you. U have to figure out ways to achieve it. Sometimes u need to experience it yourself.
