Experienced full stack web/app developer and very active in open source; I mostly have experience with Javascript (front/backend), general web development, and Android development. I also have UI/UX experience, and worked as a designer for two years, so you can hire me to make an entire product. My open-source projects are used by over 100,000 people in 200+ countries.
I do take on - and even prefer - small jobs, and I don't have a minimum. Previous clients have even hired me for just a half an hour to find ways they can optimize their site.
Native English speaker, and dual US/Dutch citizen, so I can work in all of Europe and the US - the majority of the developed world - without any visas, permits, etc etc. I live in probably the most central spot in Europe; I can be in Rotterdam/the Hague within 15 minutes, London/Brussels within an hour, or Paris/Berlin/Zurich/Copenhagen within two hours.
