Tim te Beek

Staff software engineer at Moderne, where I'm the community lead for OpenRewrite.

[Tim te Beek @TimteBeek]

I’m excited to announce I'm joining @moderneinc to work on @OpenRewrite!

What started with Open Source Contributions a year ago, and grew into conference speaking, has now ultimately brought me working there full-time.

I can't wait to see where this will go!
