Due to personal problems on the part of the performer, it was necessary to terminate early in order not to waste each other's time.

I planned a simple project for ~$100, but after consulting with Andriy Tsapenko, I agreed to a more complex solution, costing almost 38,000 UAH and with a completion time of 11 days. From the start, the impressions were positive: Andriy skillfully analyzed the task, proposed a technically strong solution, justified the choice of stack, and distributed the time step by step.

But in practice, there was no result. Throughout the entire period, Andriy communicated at most once a day and each time only promised that everything was in progress. On the 11th day, the project was not ready. He asked for another 3 days — I agreed. But again — no code, no evidence of work done. Just promises.

19 days have passed since the start, payment was made through an escrow service, but I received neither a line of code, nor a demonstration of progress, nor screenshots — nothing. Just constant assurances of "it will be ready tomorrow." No specifics, just delays.

I am forced to cancel the project and leave a negative review. I do not recommend working with this contractor if you value deadlines, transparency of the process, and respect for agreements.
