I came across this term many times “freelance designer”, Who is freelance designer and how he works? Does freelancer develops his own product and sells it to the company; How one can become a freelance designer? Any examples.
A freelance is self employed (not a full time employee). Maybe the most common way is to work either on-site or off-site getting paid by the hour. Sometimes can also be a fixed fee for reaching specified project goals.
