LinkedIn has a clear advantage here over the other freelancer marketplaces (Fiverr, and Upwork) especially in the unsaturated specialized knowledge sub-fields of technology. Although this feature will be gamified, in the first year at least, the freelancers (assuming they are existing LinkedIn Users) available on the platform will have:

  1. Somewhat reliable employment history
  2. Similarly reliable educational credentials
  3. Code contribution metrics available via a Github integration
  4. Reviews provided by authentic customers who also have LinkedIn accounts

A simple verification process here will ensure that the reviews are authentic, thereby ensuring trust in the ratings of each freelancer.
