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. ”
Stephen Vasallo
Co-founder @ Bubble
“We needed a programmer to help push a project over the finish line, and I figured -- best case -- Toptal would find someone who would come in and complete a few tickets. Instead, Sergio blended right in with the team and made significant progress after mere days of ramp-up. He even offered to take his laptop with him on vacation in case we had a customer issue with his code! He surpassed my expectations, and then some.”
