“Chris is an absolutely exceptional Python developer, and the single most efficient programmer I've ever worked with. From the beginning of the project, Chris was instantly a vital member of the team. He's proactive, self-managed, knowledgeable, and efficient. I point him in a direction, and he delivers. Chris will be a part of the Crisis Cleanup team as long as I have anything to say about it.”

“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.”

“We have been with Toptal for over two years and have hired through them multiple times. They've never failed to deliver with world-class talent and customer service and have been our first choice when scaling our team.”

“I'm incredibly impressed with Toptal. Our developer communicates with me every day, and is a very powerful coder. He's a true professional and his work is just excellent. 5 stars for Toptal.”

“Toptal provides a great service: Within a week of posting my job, I was matched with my developer and ended up completing the entire project with him. I'll continue to use Toptal in the future for any new development work I may need.”

“Toptal was the best thing to happen to my web app. Initially, I hired a team of freelancers from India through another freelancing website—which was a nightmare. In fact, it was so bad that I had to start again from scratch, which is when I found Toptal. The experiences were like night and day. It was so refreshing to get partnered up with a quality developer that I could trust due to Toptal's extensive screening process. I will only use Toptal from now on and highly recommend you do the same.”

“I really enjoyed my experience with Toptal. Searching for a developer was both painless and engaging, and the first match was a perfect fit! Toptal is a fantastic way to find talented developers for small or large aspects of your project.”

“With Toptal, we are able to find talented developers in a matter of weeks instead of months. The quality of talent they supply is extremely high as the developers are able to immediately onboard and ramp incredibly fast.”

“I've been very happy with Juraj. He is efficient, writes great code, and is an extremely nice guy to work with. Most importantly, he is self-motivated -- in his initial pass at the code base he has contributed several optimizations and stability improvements.”

“Dave as a developer was absolutely fantastic! The guidance that he provided us will allow us to make tremendous improvements to the next version of our application.”

“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.”

“Toptal has been extremely helpful to us in finding top remote talent. The ratio from interview to hire with Toptal candidates is the highest I've ever experienced in my professional career.”

“We've been incredibly pleased with our experience working with Toptal thus far. Their team worked quickly and efficiently to isolate the needs of our project, and they paired us with an appropriate developer within a couple days who we quickly contracted after a great interview. The work performed on our project was top-notch, and we can’t wait to make use of Toptal’s resources again.”
