Become a sponsor to David Leuliette

Hi, my name is David but on the internet, I’m mostly known as flexbox.

I'm a designer and a bootcamp instructor specializing in cross-platform application development.
I share a lot of application examples that you can find on my GitHub profile.
I also do some cool sketchnotes about tech conferences available on my personal website.

In the last few decades, I've spent a lot of time and money creating content that is free for everyone to use and learn from. If you'd like to show your appreciation or just offer me a coffee, consider becoming my sponsor!

1 sponsor has funded flexbox’s work.


Since I'm just getting started with open-source, I would love to have 10 sponsors so that I can devote more of my time.
