Stuff subscribers say...

I can honestly say that your videos have helped me take my development abilities to the next level.

A couple of years ago... we started discussing [an] episode every week... from API design to making code more readable, addressing security concerns or how to build the best test suite for your applications... we decided to spend 30 min per week discussing the current episode and how we implemented that particular concept into our projects. We've been doing this every week for six years now 🤯

I honestly can’t recommend Avdi’s courses enough... even if you’re a grizzled old grumpy dev like me I guarantee you’ll learn a ton of [stuff] you can put into practice immediately

I've watched a lot of screencasts and online courses over the years and have authored/recorded many myself. [Graceful.Dev] is some of the most well-crafted and interesting content out there.
