Your talk idea is good. Your abstract might be killing it After reviewing hundreds of CFP submissions, here's what makes the difference: ✅ Lead with the problem, not the solution ✅ Be specific about the audience ✅ Tell us what attendees walk away with ✅ We actively want new voices vdams27.cfp.dev

The CFP is officially opened at @devoxx.com 🤩 Submit your session (wisely) The earlier you submit, the better your chances. We can’t wait to see what you’ll bring to the stage! amsterdam.voxxeddays.com#speak 31 March – 1 April 2027 #vdams27

Episode III: The return of the engineer AI is changing the way we build software. Tools are getting smarter and development is getting faster but software still needs good engineers. Save the dates: March 31 & April 1, 2027 Discover our new website: amsterdam.voxxeddays.com Are you ready?
