There are several upcoming conferences that are looking to feature presentations from customers about their experience developing with Oracle tools.
If you are actively developing applications with Oracle ADF (or other Oracle technologies) consider submitting an abstract sharing your experience.
What works and what doesn't? How did you train your people? What's your development process? Do you do any cool things? Did you migrate from another technology and how did it go?
Speakers usually get a free pass to the conference - so this is also a nice way for your company to save on sending you to a conference to learn from others.
Some of the conferences with open call for papers
User group conferences are a great place to take your first steps as a speaker.
They want to hear from real users about real use cases, and you have what they need!
