Rasmus delivers and is fantastic to work with

"Rasmus delivers and is fantastic to work with. It took him about 0.2 seconds to understand my vision, and then he took the lead and ran with it at 260 km/h in exactly the right direction.
‍
He responds incredibly quickly and always with a smile, no matter how annoying or demanding I (read: I) am. He has handled crazy ideas as well as small and large requests flawlessly. And he has contributed ideas that have made the final result so much better than I had dared to hope for.
‍
I am deeply impressed that it’s possible to be so skilled and so pleasant to work with at the same time. It’s (almost) not fair to his competitors."

This testimonial isn’t justifying the output Rasmus delivers, you will have to try yourself

"We’ve worked with a lot of web-people, but they have always fallen short. Rasmus has not.

Besides being an overall nice guy with a great sense of humor, Rasmus is a machine. I’m wondering whether he is human or a robot.

Working with creative people is hard, I'm a creative myself. But the way he scopes projects and delivers on them is out of this world. He has taken so much stress off my shoulders and has secured the performance of our site and our company.

This testimonial isn’t justifying the output Rasmus delivers, you will have to try yourself."
