Danil is a wonderful developer. Trust my extensive freelance experience (over 500 completed projects here): specialists like him are hard to find. If all developers worked like him, the world of development would be significantly better.

Specifics:

– Danil was always in touch.

– He accepted all feedback.

– He made adjustments quickly.

– He read the technical assignment correctly.

I am satisfied with the work and can recommend Danil as a Node.js developer. I hope we will work together with the same success again. Quality, deadlines, communication — everything is top-notch, so 5 out of 5. I look forward to long-term cooperation in the future and hope that our collaboration was enjoyable for Danil.
