Hey Otu, thanks for commenting!
If you're looking to get hired, there are plenty of job portals out there you can use, but I would start with LinkedIn. Make sure you have a good profile there, complete with a good picture, description of what you know how to do and links that showcase your experience.
As for projects you can work on, I would say things like:
Taking just those 2 types of projects, you can give them specific tasks and implement many different variations. Also, what technology are you going to focus on? For back-end (which I'm assuming you mean web back-end) you have some great ones like Node.js, Python, Ruby even PHP. Pick one and focus on that one for the time being. That would be my advice.
