Have you tried https://leetcode.com or some of the interview prep sites like https://www.interviewcake.com ? Also with such little funds left (not judging, I'm in a similar situation myself) have you tried doing some less-than-awesome work on Upwork or Toptal?

Does your Github profile show your quality of work? I get a lot of job offers based purely on my Github profile, although I'm currently trying to launch a startup so I'm not accepting many.

What are your most marketable skills? Are you willing to learn new skills? It seems that ReactJS is in high demand, even if the framework is a bit funky IMO
