droidcon Berlin 2021 — Presentations

I’ve had a fantastic week at #dcbln21. I couldn’t ask for a better event for us to be once again together. I’ve had the opportunity to meet numerous people in person and remember how good it feels to talk to a live audience.

Now that I’m back to reality, I wanted to check a couple of slides from talks that I’ve watched and as I was bookmarking them, I’ve decided to go that extra mile and try to gather them in a single post.

Note: if you’ve found slides that are not here, please add them in the comments, that I’ll update this post.
