Rooted in Excellence.
QCerris is a team of hard-core technologists and architects of digital success stories, with a proven track record since 2017. Our name comes from Quercus cerris - the cerris oak - a symbol of strength and resilience.
Born in Chicago.
Built for the world.
Our story began in Chicago when a team of tech veterans and entrepreneurs identified a gap in the market. QCerris founders, with years of hands-on experience across North America, realized that enterprises needed more than IT contractors - they needed a real engineering partner.
QCerris, LLC. is a U.S. firm headquartered in Delaware, with our primary engineering and delivery center at QCerris D.O.O. in Belgrade, Serbia - home to some of Europe's finest engineering talent.
Today we are 120+ architects, engineers, and specialists, with offices in three countries across two continents.
