Vadim is not a great developer, he took a long time than expected but still did not complete it. Unfortunately wife got COVID and was in emergency situation that pushed me to release a huge amount without even getting the work completed. No new developer is accepting to fix it , as they say there are a lot of work pending ! Very disappointed and lost my money. I hope this money was used for his wife.

Great guy to work with. Every change I asked him to make, he did it. There were multiple iterations we had to go through to maintain the consistency, Vadim made all those iterations very easily. Thank you so much, Vadim.
