Describing myself in a few bullets:

  • Dutch 🇳🇱
  • Software architect by day (mainly C#)
  • Home automation enthousiast by evening/night/weekends

Last few years I developed a lot of small applications revolving around the house.

More home automation ⭐️

A lot of people use my libraries, my sonos-text-to-speech server has over 48k of pulls on dockerhub. And sonos2mqtt has over 237k pulls. Those are some big numbers. I would like to spend more time on developing those apps to automate your (and mine) house, people sponsoring me would allow me to do just that.

Sonos party mode 🎉💿

I’m playing with the idea to build a Sonos party DJ app, where all your guests can vote for the next song. TV display with the current and next 3 songs with their vote count, admin screen to set things up and overrule the queue and a simple voting screen.

Having a lot of sponsors would help me devote time to this awesome idea.

Recurring or One-time sponsoring?

I have some monthly and some one-time sponsoring tiers. Pick the one that fits your budget. Your support is greatly appreciated!

More info

Recently I've created my Github pages website it has even more information about me and all my projects.

Checkout all the other repositories or npm packages.

European companies 🏢

If your company would like to sponsor me, I'm able to provide you with an official (Dutch) VAT invoice, but please contact me up-front to get the correct details. Fellow Dutch people, I can also send you a tikkie, just send me a message with the amount you would like to sponsor.


Reaching ten sponsors would really motivate me to spend some more time on open-source home automation stuff. 🤩 I really want to build a Sonos party dj app, but time is some what limited right now.
