Testimonials
“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 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

On multiple occasions, we needed to alter our timeline and they never hesitated to accommodate us. Bojan was communicative and delivered what we asked for on time and exactly to spec. I know that should we need additional work, will surely be looking to hire Bojan and Toptal again. ”

I give Michal and Toptal my highest endorsement and will continue to use and recommend them to anyone looking for software engineering talent.”
