Cortlex is an IT service company founded in 2015 by developers for developers. It gives us an opportunity, as founders know what is needed for comfortable and pleasant work. They are fully involved in all processes (for example, they are mentors, conduct interviews) and sit in the same room (or in the next one) with you. It means that you can discuss any issue related to the company, projects with them.

All projects are in English (mainly in Western Europe, the USA), we become a full-fledged part of the customer’s distributed team: we clarify requirements, discuss architectural solutions.
