Where can I learn tech skills to use in a sandbox?

Glad you asked! At Next Tech, we're working to build an ecosystem for developers. Part of this is our sandbox offerings, but we got our start as a platform for creating interactive courses for learning tech skills.
For the first few years of Next Tech's existence, we just powered the learning experiences for content companies (like textbook publishers and online learning providers). Recently, we've started to release our own courses, which you can find in our course catalog!
A large number of courses in this catalog are built based on content from our partner Packt Publishers. If you're interested in a specific subject area, feel free to check out Packt's website, and just drop us a note using the message bubble with your wishlist! Your feedback will help inform the next courses we focus on developing.
