  I have been working with Upstaff for over a year on a project related to landscape design and management of contractors in land design projects.

  I worked with Upstaff engineers for over 2 years, and my experience with them was great. We deployed several individual contributors to clients' implementations and put up two teams of upstaff engineers. Managers' understanding of tech and engineering is head and shoulders above other agencies. They have a solid selection of engineers, each time presented strong  candidates. They were able to address our needs and resolve things very fast. Managers and devs were responsive and proactive. Great experience!
