this is a terrible specialist
they divided the project into two parts
the first part was not completed even by 10% but we closed the project so she would work faster
and then it started
sometimes there is no light for weeks, sometimes something else
we paid 10,000 UAH for the first project and it was in vain
the feedback is more negative
the maximum that can be trusted is to create a logo for the group on social media
