Testimonials
“Marcos was a wonderful engineer and really helped us out on this project. Without him I feel like we really would have been at a loss.”
Jama Mohamed
Owner @ JM Technologies
“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.”
Jason Kulik
Co-Founder @ ProHatch
“Toptal makes finding a candidate extremely easy and gives you peace-of-mind that they have the skills to deliver. I would definitely recommend their services to anyone looking for highly-skilled developers.”
Michael Gluckman
Data Manager @ Mxit
“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, it was at a fair price, and it came with a much appreciated, risk-reducing trial period.”
John Olsen
Director @ Bingo Solutions
“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 just his initial pass at the code base, he has contributed several optimizations and stability improvements. Regarding Toptal as a service…well, you matched us up with Juraj without me having to sort through a list of candidates, so I’m impressed.”
Matt Cotton
Dev Team Lead @ eFolder
“Our Toptal contractor quickly came up to speed on our process and became an integrated part of our team. We look forward to growing together!”
Vitaly M. Golomb
CEO @ Keen Systems
“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. ;)”
André Fischer
CTO @ App Promotions
“We really enjoy working with Toptal. The experience has been very positive, and we'd recommend it to anyone seeking developers on-demand.”
Jeff Kerr
CEO @ CaseFleet
“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.”
Chip O'Toole
Founder @ Humans Helping Robots LLC
“Toptal's developers and architects have been both very professional and easy to work with. The solution they produced was fairly priced and top quality, reducing our time to launch. Thanks again, Toptal.”
Jeremy Wessels
CEO @ Kognosi
“We're a small firm with big dreams. After trying 4 or 5 local or outsourced developers, we were out of options. I'd heard of Toptal, but was worried that my company wasn't big enough for them. After calling them up, I found out that I didn't need to meet any minimum budget and was immediately put in touch with a developer to talk through my problems and goals. A day later, he got back to me with a list of possible solutions. After 9 months and 5 developers, Toptal got me my solution in a single week at a price I could afford.”
Kevin Ramirez
Co-Founder @ SixtyVocab.com
“It has been wonderful to work with Fabian for the past two years. He is an expert in JavaScript development and has built our embeddable widget and video player. He is a quick study and is able to learn how to integrate new technologies, which is so critical for a startup. He even took the extra effort to teach others on the team. He is super responsive and often went above and beyond to help us meet deadlines (including working on weekends). Thank you Fabian. Thank you Toptal for making it so easy to find and work with amazing talent.”
Natasha Mohanty
CTO @ FEM Inc
“Nuno is brilliant! He has been extremely helpful and really knows his stuff with regard to Django in particular.”
