Hey Renato, good talk!

Dealing with API’s is becoming a more and more frequent tasks. So it was inspiring to learn about GraphQL and the problems it solves. Your slides where nicely animated and aside from the 1 typo and the GraphiQL moving being “too big for the screen” I appreciate the care and quality of your slides.

Some tips, we’ve already been over these personally yesterday:
- Consider moving the n+1 (http overfetching) chapter of your talk to the beginning. It gives you and the audience way more room to explain what GraphQL is and how the syntax looks. Pagination was a bit to hard for me personally to just drop into. Showing the basics first gives a better approach.
- When explaining stuff, talk more slowly and allow the audience to “process” your point before moving on to the next one. A short break of 2 seconds or scanning for a nod in the audience might help to get this timing?
- A hard part during the pagination chapter was the introduction of the “edges”. This turns out to be a configurable keyword. Be sure to explain that before moving on.
- I prefer a plain HTTP request so I can see the difference between the, all-to-familiar REST.

All points are from my personal view and do not guarantee the opinion of others. Maybe the tips can help you. Good luck and thanks again.

Interesting talk, I really want to dig in deeper now. Good examples. Well presented overall, but you might want to slow down a little. Adding examples about security layers would be of interest I think.
