Testimonials
“Dario was recently assigned to our company in order to help with PHP and JW Video player refinements. He listens extremely well and offers common sense suggestions that save both time and money. He speeds up the process by asking great questions, and he just delivered our first project on time. His redesigned player offers a very pleasing appearance and delivers functions that are both elegant and intuitive.”
Dennis B. Jacobs
President @ College TV Ticket
“Toptal’s ability to rapidly match our project with the best developers was just superb. The developers have become part of our team, and I’m amazed at the level of professional commitment each of them has demonstrated. For those looking to work remotely with the best engineers, look no further than Toptal.”
Laurent Alis
Founder @ Livepress
“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

Jeff Kerr
CEO @ CaseFleet
“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.”

“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin
Chief Technologist and Co-Founder @ PriceBlink
“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
“FundedByMe needed to quickly scale our development team to create the equity crowdfunding leg of our operation. Working with a small budget, we couldn't spend time on vetting candidates, so we turned to Toptal. They identified a stellar developer that truly set the bar when it came to delivering product.”
Arno Smit

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.

Stuart Pocknee
Principal @ Site Specific Software Solutions
“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!”
