As a front-end developer I worked closely with Jonas for a couple of months during the spring of 2013. Jonas held two essential roles, he was both technical project manager and scrum master. Even though that is a challenging balance he managed to steer the ship and we launched a fully responsive multi-language corporate web for Bisnode that the client was more than happy with. Jonas is a dedicated professional, humble, creative, and effective. I positively recommend him and would be happy to collaborate with him again.
