"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."
