When we contact one of those companies, we never mention you or show them your profile. Our public pages also show anonymous summaries of our vetted engineers (by skill, level and availability, never a group of fewer than five) and blind profiles without your name, employer or contact details (they show your seniority, experience, skills and your working-hours overlap with US Eastern time); email team@ruzora.com to be left off every public page.
