Become a sponsor to Kevin Jahns

Kevin Jahns

Berlin, Germany

Hi, I'm Kevin from Berlin 👋

I'm an independent software developer working full time on Yjs and related projects. I'm not backed by a company or any grants. Please support my work financially if you use it.

Are you using Yjs at your company? Great! Convince your employer to buy a support contract (500$/month). I will prioritize your issues and we can hang out on weekly zoom sessions. Thank you!

55 sponsors are funding dmonad’s work.
