(ASK) Learning design as a developer

Hello HackerNews,

I'm a full-stack engineer who has started taking on a product management role at my start up for a user facing application.

I'd like to embrace the product management work, and part of that seems to be spending a lot more time thinking about design (and working with our freelance designers).

Does anyone have recommendations for resources, whether they be online classes, blogs, or events (Berlin based), where I can start giving myself a design education.

Cheers
