Description

👋IT is not just a job, but a childhood passion that I have been cultivating for over 12 years. The technical development of a project is a challenge that I never tire of.

I have continuously supported companies from the inception of a project to the release of a finished product, covering all aspects of its realization.

I am convinced that a developer's role is not just to "code" but also to guide stakeholders in making the right technical choices for the successful completion of projects.
