A freelancer is a self-employed individual who offers their services to clients on a temporary basis. They are not employed by any specific company or organization and instead work independently. Freelancers have the flexibility to choose their own projects and clients, set their own rates, and work from any location. They can offer various services such as writing, graphic design, web development, consulting, and more. Freelancing allows individuals to have control over their work life and schedule, but also requires them to handle all aspects of their business, including marketing, invoicing, and client management.
