I recently heard about a free online conference for web developers called backendlessconf_. It's hosted by ZEIT (zeit.co) and their CEO Guillermo Rauch will be speaking at it along with many others. I heard a great talk from Guillermo Rauch a few weeks ago at the GitHub Universe conference in San Francisco, so I'm looking forward to attending a conference that he has helped put together.
The conference is happening next Saturday December 14th (2019). You can register for it (for FREE!) here: https://backendlessconf.com/.
This will be my first online conference so I'm not sure how it will compare to an in-person conference. If you've attended an online conference before I'd love to know what you thought of it (and what conference it was). Feel free to leave a comment with your experiences!
