Presenting

We are always looking for speakers for the Boulder Ruby meetup. Presentations are expected to either be 15-35 minutes long with questions, or a 5-10 minute lightning talk. Topics can be either anything rubyish/rails or software development. (We've had presentations on k8s, machine learning and interviewing, for example.) See above for more examples of past presentations.

It's a friendly group. Audience is typically 15-40 folks depending on topic/speaker. The audience experience level varies from "I just graduated from Turing" to "I help run railsconf".

If you are not in the Denver/Boulder area, we have the equipment for a remote presentation (Zoom or Google Hangouts). Tweet us or contact Dan Moore at mooreds+boulderb@gmail.com to discuss speaking, or if you have more questions.
