“I struggled for weeks with a Youtube API-specific problem and couldn't find anyone to solve it. Toptal immediately identified the right consultant who took the time to investigate the issue and resolve it quickly. The process was seamless and I will continue to use Toptal with any other issues that arise.”

Xavier Xicay
CEO & Creative Director @ Tuatara Corp
“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.”
Bryan Adams
CTO @ Healthsense
“Toptal is a great resource for startups with ever changing product roadmaps and budgets. We had highly skilled and reasonably priced Toptal developers working for us within 8 business days of our first conversation with Toptal. It has been an empowering experience for our company to start working with Toptal.”
Chris Clark

He brings an enthusiasm to his profession that is very refreshing, constantly surprising us with his depth of knowledge and his capability to not only complete the task, but to surpass our expectations. He presents us with solutions that we would not have thought about ourselves, and sees the problem better than we can explain it.”
Chad Berryman

Carter Cleveland
CEO @ Artsy
“Working with Marcin is a joy, I can't find a better word. He is competent, professional, flexible, and extremely quick to understand what is required -- and to implement it -- even if the source code that's given to him is, shall we say, less than optimally elegant and clear. Oh and he has the same sense of humour as me. ;)”
