Alexis did a fantastic job. This is a mega professional of your business. He responds to the messages almost instantly. We spent more than 4 hours on the video link to remotely write MySQL query (query) and draw together several tables from BD for subsequent visualization. To say I’m happy means not to say anything. above all praise. I will definitely address him with projects in the future, and I strongly recommend Alexey to other customers who need a specialist in working with BD.
