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.”

“Andrea is doing an amazing job. I don't think we could have gotten a better person. He is fun to work with, he thinks out of the box, and he is extremely knowledgeable in what he is going. 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.”
