Testimonials
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin

“Working with Enrique has been a pleasure and a relief. His knowledge in the IT space is broad and in-depth. Zoomedia has been in need of this level of support for some time and I feel confident we are an exponentially stronger team with Enrique on board.”
Justin Bane
Senior Technical Lead @ Zoomedia
“One of our most time consuming problems is finding qualified staff. We need to find the correct platform to advertise on, create a proper ad, filter through tons of applications, interview and test the applicants' capabilities, and finally take a risk by hiring. This was the old way of doing things. The new way: describe the job position to our Toptal account manager, interview a few qualified applicants, and hire with a risk-free trial -- much faster, a lot easier, and with incredible results.”
Catalin S. Balaci
Owner @ EvoBits Information Technology SRL
“We've been very pleased with our experience working with Toptal. Their team was incredibly helpful in finding us the perfect developer for our project. The work was stellar, the communication was excellent, and we couldn't have been happier with the overall experience. We're excited to work with Toptal for more projects in the future. ”
Ryan Walker
Director, Product Management @ Rand McNally
“When you're growing quickly and your internal resources are strapped, you need to find a way to move forward regardless. We couldn't have done it without Toptal. From content creation to programming and design, we were able to leverage the expertise of Toptal's network to move even faster that we could have otherwise. They prioritized finding us the right person, not just a person. Every single one they introduced us to was not only qualified and professional, but also eager to help us.”
Josh Leskar
Manager @ Udemy
“Toptal makes finding qualified engineers a breeze. We needed an experienced ASP.NET MVC architect to guide the development of our start-up app, and Toptal had three great candidates for us in less than a week. After making our selection, the engineer was online immediately and hit the ground running. It was so much faster and easier than having to discover and vet candidates ourselves.”
Jeff Kelly
Co-Founder @ Concerted Solutions
“As an internet marketing company specializing in pay-per-click management, our clients frequently ask us to provide services that fall outside the scope of our primary business.
