Upwork  

Upwork is one of the oldest and most popular freelance marketplaces that connects millions of employers and independent contractors from all over the world. Upwork is the perfect example of what the modern market of freelance marketplaces calls a generic bidding marketplace. And although this model proves to be popular for some, throughout the years both freelancers who get jobs from Upwork and clients who want to hire remote or part-time employees have discovered that it also has some flows.
