Speaker registration & slides
Propose a talk and manage your slides privately with the organisers. Please also complete the main event application above. A speaker submission does not confirm attendance or a speaking slot.
After submitting, open the private link sent to your email to confirm your address, upload a PDF or PPTX slide deck, replace it later, or mark it as not ready. Slides are shared only with authorised organisers.
