If you are a freelancer that is looking for any computer technology work, then I think you can find that kind of job on most freelancing sites such as fiverr, Upwork and the rest. I am a writer and have worked on some of those sites such as freelancer and I have to say that there are series of jobs that you can do on it. The thing is that you need to register and setup a professional profile that is going to show clients that you can be able to deliver the work at the stipulated time.
Also, getting some of the samples of your work ready is something that you should also try to do since most of the clients will want to see what you have done in the past before giving you any work to do for them. The reason for that is to ensure that you don't end up doing a bad work that they won't like. So, search some of those freelancing sites that I mentioned in order to start bidding for jobs immediately.
