“I have worked with Tanja on the Healthy Workers project and am very impressed with her skillset and seniority. The project was already on it’s way for 1 year.

Tanja grasped the vision, idea and expectations really quick. She took on her role as senior, lead the ux team and started building in the first week until the end of the project.

She delivered more then promised. I recommend hiring Tanja for any high end UX job !”
