requirements for getting a remote job

Can someone provide valuable insight about how to get a remote job in MERN development? What are the difficulties someone can face? How to apply/get referrals for the Job opportunities.? Any Job portal where they hire from? What salary range I should expect? Note- I have industry experience of about 1.5 years but not in Web development (MERN). I'm learning MERN on my own and making some end-to-end projects.
