The author realized that their approach of micromanaging engineers and not allowing them to make mistakes was detrimental to employee morale and growth.
They decided to change their approach by allowing engineers to submit pull requests and reviewing them before pushing to production.
If a bug occurs, it is either forwarded to the engineer to fix or fixed by the author if time-sensitive.
The author now trusts their engineers to do their job and feels relieved to not be the only expert on the codebase.
