If you want to hire experienced developers (at least strong and confident Middles or Seniors), you’d better look for the platforms that explicitly state that they don’t accept newbies. There’s nothing bad in Juniors as such (eventually they can turn into star Seniors!), but if you have strict hiring requirements, they slightly blur the scene. Our recommendation of the marketplace that accepts only Middles and Seniors is Lemon.io. Created in 2014 as a small friends-only startup called Coding Ninjas (performing mostly WordPress tasks), it grew into one of the most prominent vetting marketplaces in Ukraine. Lemon.io doesn’t accept any IT freshmen: only Middles and Seniors are accepted. Its clients are American tech startups, and they need proficient coders to get things done. US clients seeking tech-savvy pros needn’t additionally filter them by proficiency and experience level: Matching and Recruiting departments will do everything themselves.
