AmazingHiring sorts candidates based on the consolidated rating that is calculated as a weighted sum of 20+ criteria, with the 3 most important being evaluation of technical skills, rating of the current employer and level of seniority.
You can sort candidates by their achievements on professional sites: Github, StackOverflow, Kaggle, Google Play. These sortings allow you to see the fresh faces on the market. In the top of the search output you might see not only the senior developers working for the leaders of the market, but also aspiring developers who are active and successful on Github, StackOverflow, Kaggle and Google Play.
Please keep in mind that in order to sort candidates by Kaggle rating, you need to enter "machine learning" in the skill section in the search query. Enter Android as a skill if you want to sort by Google Play rating.
