The project was completed on time, this is the first, but not even the main thing, I searched for a long time for a person who would do the project on different hardware (different people promised to do everything and disappeared after trying), but Alexey offered me a more optimized option with development prospects, as it turned out he was right 100%, overall he is a person who knows exactly what he is doing, without fluff and "it won't work, I am not familiar with that". Ten out of ten stars.
