You may have already done some kind of work to supplement your income at the end of the month. Or maybe you know someone who quit their job to work alone. This type of activity is called freelancer.
Freelancer, or freela, is a professional who works independently providing services to companies or people during certain periods of time. And when these jobs are done exclusively through the Internet, they are called online freelancer.
Unlike a traditional worker, the independent professional has no employment relationship with the company or the person who hires their services.
As a result, the service contracts have a fixed duration, according to the availability of the professional and the demand of the client. Even so, the employment relationship can be recurrent if both parties are interested.
And since the freelancer has no employment relationship, he can work serving several clients at the same time.
