Testimonials
“We needed a expert engineer who could start on our project immediately. Simanas exceeded our expectations with his work. Not having to interview and chase down an expert developer was an excellent time-saver and made everyone feel more comfortable with our choice to switch platforms to utilize a more robust language. Toptal made the process easy and convenient. Toptal is now the first place we look for expert-level help.”
Derek Minor
Senior VP of Web Development @ Networld Media Group
“I'm incredibly impressed with the caliber of the Toptal developers I have worked with - they have proven themselves to be both dedicated and highly talented. We will most definitely continue to work with Toptal. ”
Savannah de Savary
Founder @ Industry Hub
“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

In just over 60 days we went from concept to Alpha. The speed, knowledge, expertise, and flexibility is second to none. The Toptal team were as part of tripcents as any in-house team member of tripcents. They contributed and took ownership of the development just like everyone else. We will continue to use Toptal. As a start up, they are our secret weapon.”
