Hey there 👋

My name is Jan Küster and I am all about JavaScript JavaScript Icon and Meteor Meteor Icon

I love to work on projects, that are about education. I currently work on, a diagnostic and learning platform for German adults with low to very low literacy skills. The target group is employed adults, which are limited in their career path due to low fundamental literacy skills.

I am also a constant contributor around Meteor and it's packages ecosystem. Recently I joined up with Storyteller CZ and Alim S. Gafar for the weekly Meteor.js Community Podcast on YouTube.
