"Out of all the vendors we work with, DevsData clearly stands out. The quality of developers they deliver is beyond what we've received from any other vendor, and they've been able to send profile recommendations very quickly. I'm happy to be their reference for other companies from Israel and talk about their recruitment abilities and what they delivered for us - we eventually signed over 19 engineers from DevsData. I'm extremely satisfied with this recruitment process."

Best back-end engineers I've ever worked with.

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly.”
