CJ Avilla

Hey! I'm CJ Avilla and I help beginner and mid-level web developers learn how to build web applications and API integrations. If you're just getting started or are looking for some specific API integration examples, you're in a great place.

On this channel you'll find content for learning how to program, computer science fundamentals, and how to work with APIs. Sometimes my sons and I livestream building games.

Most content is a mix of several programming languages like ruby, javascript, python, php, go, c#. We'll also play with different frameworks like React and Angular.

CJ (Christopher James?), you are truly the best. An outstanding educator. You teach us exactly what we need to learn: how to navigate through even the most abundant documentation, which is an art in itself. An art that you share exceptionally well, illustrating it wonderfully. Your teaching methods are excellent, and you are an excellent teacher (and this comes from someone who loves pedagogy, saying this with joy). Thank you for everything, from France.

It's 2023 and this still remains VERY relevant. Developers seem to forget that there is a TON of legacy .NET Framework 4.8 and earlier code that is still reliable, running and in production, and will be probably for another 10-15 years entirely as-is with no plans to "upgrade". So if developers suggest STRIPE as an alternative, but there's no good sample code for implementing it, they will have to move on to something else. This was great, but you skipped how to handle the results.

Hey I'm excited to work through this playlist. Thanks for putting this together. I'm sure it will become clear later, but I'm wondering why you chose to have a database backed version of your videos at all. It seems like it would make more sense for your models to just be POROs that are just backed by API calls. Will keep watching!
