This is the newsletter that gives you a summary of everything relevant that happened the past week that can help you on your coding journey. Be sure to tell me what you think.

Early morning and a lot to talk about.

Last week was all about Imposter Syndrome. Having recently switched jobs and started working with a whole new team, this feeling was intensified. It is something that usually comes and goes but there are ways to future-proof yourself against it, and I made content around exactly just that.

The key point to remember here is that it is a very common phenomenon and you are not alone.

If you’d like to talk about that with someone, I am available for it. My DMs are always open on Twitter so feel free to hit me up.

Now let’s start this week off with the right foot 🦶

Also, I got a kitten! 🐱
