“In addition to sharp technical skills, Faruk had a great attitude and is a really exceptional communicator. He always let us know where he was with his work, thoroughly and reliably. That's not always the case, and it made working remotely considerably easier. He was an easy integration into the team. ”

“Through Toptal, we were able to find and select a senior engineer who is both very professional and easy to work with. The quality of matching that Toptal enabled has been crucial to our success, was at a fair price, and came with a much appreciated, risk-reducing trial period.”

“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. We have found Toptal to be exactly the resource we need to connect with contractors so we can deliver our clients top tier web development talent at a reasonable cost.”

“I'm incredibly impressed with Toptal. Our developer communicates with me every day, and is a very powerful coder. He's a true professional and his work is just excellent. 5 stars for Toptal.”

“The best talent is at Toptal for sure. It's way better and faster than any other means of getting top talent.”

“The developers I was paired with were incredible -- smart, driven, and responsive. It used to be hard to find quality engineers and consultants. Now it isn't.”

“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.”

“Toptal understood our project needs immediately. We were matched with an exceptional freelancer from Argentina who, from Day 1, immersed himself in our industry, blended seamlessly with our team, understood our vision, and produced top-notch results. Toptal makes connecting with superior developers and programmers very easy.”

“We needed a programmer to help push a project over the finish line, and I figured -- best case -- Toptal would find someone who would come in and complete a few tickets. Instead, Sergio blended right in with the team and made significant progress after mere days of ramp-up. He even offered to take his laptop with him on vacation in case we had a customer issue with his code! He surpassed my expectations, and then some.”

“In our 2 years of operations this is by far the most enjoyable and productive working relationship we have had with a developer. I plan on continuing to recommend Toptal's services to other entrepreneurs I run into.”

“As a Toptal qualified front-end developer, I also run my own consulting practice. When clients come to me for help filling key roles on their team, Toptal is the only place I feel comfortable recommending. Toptal's entire candidate pool is the best of the best. Toptal is the best value for money I've found in nearly half a decade of professional online work.”

“We've used Toptal developers multiple times for multiple projects, and they've always been world-class—regardless of whether they've been from South Africa, Brazil, or the United States.”

“Working with Marcin is a joy. He is competent, professional, flexible, and extremely quick to understand what is required and how to implement it. ”
