 In my work at [iZettle](https://www.izettle.com/) I spend most of my time enabling the dev teams to shine. Working on sitespeed.io is a great complement, letting me get my hands dirty with range of tools and techniques; from [controlling browsers with WebDriver](http://www.browsertime.net) to [learning how to use Docker](https://github.com/sitespeedio/sitespeed.io-docker).

I was intrigued by this tool and decided to learn more. Wanting to contribute back to the open source community that has giving me so much over the last decade, I reached out to Peter and Tobias to assist with the development of version 4.0.
