I am satisfied with Constantine's work.
The whole process of cooperation Constantine demonstrates a responsible attitude to the project.
Always on the communication and the process of interaction on the project is ready to adapt so that it is comfortable and comfortable for both sides.
The initial assessment of the implementation deadlines was too optimistic, but I can’t even call this a minus. Find a common compromise.
I recommend Constantin to everyone as a responsible, professional and decent developer.
