When I was new to the tech world and didn't have much experience with production systems, my main focus was to build fast.
That was the way I would measure how good a developer is.
Didn't care about coding practices, tests, logs, monitoring, CI/CD pipelines and performance as well.
Because of this, I had to spend a lot of time in refactoring modules or just fixing stuff.
It seemed like I was moving fast, but it was just because I didn't pay attention to a lot of things that I probably should have.
A senior came to me and asked me to "take my time". He said "harbari mei kyu ho".
It's been some years now and I have changed the way I operate. It's much less stressful.
Learn to productionize your code.
It seems slower, but I accomplish way more with a lesser amount of code than the younger me.
