As a project manager in an oil refinery, I often needed engineers and specialized technicians for maintenance shutdowns. What I appreciated most about Roberto (CEO, Sygma Engineering Services) was his ability to respond to urgent requests by finding us the right people. I recommend anyone to use the services of Sygma Engineering Services and Roberto.
