About createIT

We work on large, international and mature projects, frequently operating on gigabytes of data. As such, our projects require constant tweaking and optimization. Our teams are characterized by different sizes and workflow, and we offer a lot of flexibility when it comes to the choice of solutions. We mostly work with Seniors and experts in a given field, creating optimal grounds for the exchange of experience.

About role
