Mario – React, Angular, Node.js

Mario has succeeded in becoming a guru of the front-end, although he doesn't mind working with the back-end as well. He dedicated a solid part of his career to projects in the financial sector, but there are no borders for him. Without a doubt, Mario will take charge of the development process and find the solution even for the hardest tasks.
