Senior edX Architect

Ned has decades of experience building solid software to solve real problems, using diverse technologies.


Ned Batchelder, senior edX architect, joined Appsembler CEO Nate Aune for a live webinar exploring the building block of Open edx: the XBlock. They discussed everything from what they are to what kinds are available and how to create them.

The webinar involved a general walkthrough by Nate, followed by a slightly more technical walkthrough from Ned, and ended with a Q&A session.

Nate and Ned’s slides are available for you to check out here:
