HELLO! I'm Jonny

I’m a designer and engineer. Together with my friends I organize events like Nordic.js and Hackaway. I also run a business called Confetti, write open source JavaScript like List.js and speak at events.

It should be easy and fun to create a beautiful site for your event and that is why Martina, Johannes and I founded Confetti in 2014.


Each year we organize a huge party for the Stockholm tech community, we call it Festen.


Each year Martina, Johannes & I organize Nordic.js, an international JavaScript conference in Stockholm with attendees and speakers from all over the world.


I've co-organized some of the most well-known hackathons in Sweden plus a hackathon for two goverment agencys in New Zealand.


I'm co-organizer of two of the biggest meetup groups in Sweden. One for developers and one for designers.


I regularly speak at events about design, startups, open source and how to organize tech events where everyone feels welcome. Need a speaker? Drop me a mail at jonny@confetti.events.
