The term 'Freelancer's Detail' is a job description for someone who works independently and is not employed by any one company. The four-letter acronym SPEC stands for Self-Employed Professional Expertise and Competence, which is the key characteristic of a freelancer. Freelancers are typically hired on a project-by-project basis and are responsible for their own taxes and benefits. They often specialize in a particular field or industry and are able to work remotely or from home.
