Absolutely impressed with his abilities and work ethic. As a programmer myself, I needed to outsource some workload for a personal side project. I found that Vitalii was knowledgeable and very good at what he does. Also he speaks/writes fluent English, which was super helpful. I certainly will be using Vitalii again on future projects. He has earned my trust. He was actually the 2nd person I hired for this job. The first one could not complete this task as needed (even though they had a compelling resume).
Anyway, I can't say enough good things about my experience with Vitalii. If you are looking for someone who can actually do what they say they can, is easy to work with and completes projects on time, I recommend him fully.
