I had in portfolio few small PHP apps like membership sites visualising data, but I aimed at front end jobs.
However I find better is to build your own projects and showcase mainly those projects, if you just wolloed a tutorial and build a complex app and you cant really maintain it, your managers would be negatively suproced. Because everyone assumes you are master at what you are building.
If you want to take a low salary with a junior dev job, start applying NOW. And I mean TODAY. You are fare better off working as a inhouse developer that doing tutorials on your own. If you can do basics of React, APIs and AJAx mostly companies would be glad to tajke you as a junior dev for front end.
Best of luck
