I’m a freelance senior user experience and user interface Designer

I love complex design challenges (I live for this stuff). Solve the puzzle and find simple solutions that people actually love to use and help businesses grow.

Creating simple & powerful designs; pleasurable experiences for people

Designer for web since 1997 and freelance since 2001. With a specialisation in the creation of user-friendly and persuasive user interfaces. Particularly the design of complex task-interfaces (dashboards, sales-funnels and other web- applications).

‘To make it appealing, fun and easy to use and to meet or succeed conversion goals’

Intrigued by human behaviour, what triggers us, motivates us and makes us happy. I look for ways how I can remove friction and add some delight to the world.

Helping other freelancers thrive

In my spare time, I help other freelancers to thrive… to freelance better. Freelancers are skilled workers but sometimes forget to work on their (own) business too. Their are too busy helping others do well, them them realise ideas and dreams… only to let their own ideas and dreams take the back-seat.

“Maybe one day…”, they think… 

I’m here to help them reclaim time from their busy schedule. Make sure they get paid what they’re worth, negotiate better terms to stop doing to much and giving away time.

It’s okay to make more money, to be able to save for sick-days, holidays and your retirement. Make more money to buy back time so you can work on your own ideas and dreams… now.

“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 !”

Combining her innovative insight, practical work experience and knowledge, she has brought me both personal and working value. Efficiency, forward thinking and reliability are the abilities which distinguish her as a great UX designer and through which she managed to get very successful results in a short period at energiedirect.nl.
