How to invite me to do a talk. Just some ideas.

• January 30, 2026: EU Open Source Policy Summit 2026
• May 2026: Open Infra Forum, Stockholm Sweden

Look me up and say hi!

I'm generally open for suggestions and invitations to speak. Get in touch!

Traveling for, delivering and preparing good talks and presentations take time and effort and my family still wants food on the table. Don't assume I can do this for free.

Suitable for use in assocation with talks
