Irina is an excellent specialist. We ordered the development of a web3 application. She delved into the project, proposed an excellent architecture for the mobile application. She made all the necessary adjustments. She did a much more serious job than we initially planned, and all of this quite quickly. You can write to Ira at any time of the day and always expect a thoughtful and quick response. You can confidently start any project of any complexity with her; she is great.
