Ask HN: Suggestion for new team lead

To sum up, I got promotion last year and currently leading 4 people developers team.

My workdays has changed a lot, mostly preparing design docs, code reviews, creating and reviewing tasks.

I miss building features, writing codes. At the beginning it was fun but now a days I am getting bored.

My manager is happy with my role and so on.

Am I doing something wrong? How can I avoid being bored and do coding day to day not compromising my lead role.

Thanks in advance.
