    Insights into Serverless and modern backends

    Learning from tutorials is great! You follow some steps, learn a smol lesson, and feel like you got this. Then you go into an interview, get a question from the boss, or encounter a new situation and o-oh.

    Shit, how does this work again? ๐Ÿ˜…

    That's the problem with tutorials. They're not how the world works. Real software is a mess. A best-effort pile of duct tape and chewing gum. You need deep understanding, not recipes.

    I've been building web backends since ~2004 when they were just called websites. With these curated essays I want to share the hard lessons learned. Leave your email and get the Serverless and Modern Backend email series.
