He not only does an excellent job, he also helps our company to differentiate our business model further (e.g. making our app offline-capable). I would recommend Andrea as well as Toptal any time to any friend.”

I couldn't be happier with our engagement and would highly recommend Nikola and Toptal.”

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.
