Testimonials
“I've been very happy with Juraj. He is efficient, writes great code, and is an extremely nice guy to work with. Most importantly, he is self-motivated -- in his initial pass at the code base he has contributed several optimizations and stability improvements.”
Matt Cotton
Dev Team Lead @ eFolder
“We needed a talented developer and we needed him/her very quickly. So we turned to Toptal and couldn't be happier with the results! Our Toptal freelancer has contributed extraordinary knowledge, talent, and startup experience to our team. We will continue to work with Toptal to fulfill our future talent needs.”
Lindsay Fairman
Founder & Owner @ FairTech Labs, LLC
“With Toptal, we are able to find talented developers in a matter of weeks instead of months. The quality of talent they supply is extremely high as the developers are able to immediately onboard and ramp incredibly fast.”
Zac Carman
CEO @ ConsumerAffairs
“Working with Toptal has been a great experience. Prior to using them, I had spent quite some time interviewing other freelancers and wasn't finding what I needed. After engaging with Toptal, they matched me up with the perfect developer in a matter of days. The developer I'm working with not only delivers quality code, but he also makes suggestions on things that I hadn't thought of. It's clear to me that Amaury knows what he is doing. Highly recommended!”
George Cheng
CEO @ Bulavard, Inc.
“Toptal has helped my business tremendously by finding, vetting, and recruiting the talent I need, at the right time. I’d definitely recommend it to others.”
Xavier Xicay
CEO & Creative Director @ Tuatara Corp
“As a growing startup, finding top-notch engineering talent at affordable rates is one of the biggest challenges. After being frustrated with unreliable local contractors in New York, we turned to Toptal. We worked closely with Michal in Poland for 5 months and were thrilled with the results. Michal was an outstanding engineer who communicated flawlessly and took control of our project in ways that far exceeded my expectations. I give Michal and Toptal my highest endorsement and will continue to use and recommend them to anyone looking for software engineering talent.”
David Baker
Founder @ Spins.FM
“Toptal has been extremely helpful to us in finding top remote talent. The ratio from interview to hire with Toptal candidates is the highest I've ever experienced in my professional career.”
Philipp Berner
Co-founder and CTO @ KeepSafe
“We needed some short-term work in Scala, and Toptal found us a great developer within 24 hours. This simply would not have been possible via any other platform.”
Franco Arda
Co-Founder @ WhatAdsWork.com
“We recently launched our app with the help of Toptal and Nikola, an iOS developer. I was immediately impressed with the constant communication, detail, and level of talent that Nikola brought to the table. More importantly, when the project was underway, Nikola proactively provided creative workarounds for unforeseen hurdles and challenges. I couldn't be happier with our engagement and would highly recommend Nikola and Toptal.”
