My belief is that no, it wouldn’t - because the posts don’t contain identifiable information about people. I’m not an expert, though, and I’d love for someone to come and correct me if I’m wrong.
Edit: I just saw that @S4nvers gave a more detailed answer than me a bit lower down, essentially agreeing with me but quoting the relevant part of GDPR to explain why.
I got my first programming job in 1996. I still have days like this.
Today, I had a conversation with my boss about an apprentice in our team. Our senior front-end dev left a few months ago, and the apprentice has had to take on a lot of work with little guidance. Our team is very full of back-end devs with no front-end experience. During this conversation, we described our apprentice as “extremely capable but lacking experience”, and discussed the best way of getting him more experience. The conclusion we came to is that there is no shortcut here, but having good guidance from senior devs can help somewhat.
What I’m trying say here is that what you’re describing is absolutely normal, and based on what you’ve said, you’re doing fine. You have a little imposter syndrome, which seems worse than it is because of your genuine lack of experience… that experience will come with time, and days like today are the days where you learn a load from your mistakes. You’ll probably not hard-code things like that in future, and today you gained a tiny bit of that experience that you need - well done!
