I have been in current team for couple years, and feel my skills are kind of stuck because I have spent too much time fighting with the team refusing to get better. I have learned only from myself, but not much from the others, and can't really fix everything by myself.

Business and Engineering alignment

My time has been spent inefficiently to be honest in the past few years because lots of the time I was staring at smelly and nonsense codes, trying to improve but never get the resource or momentum from the team. I start feeling left behind in terms of the skills the market really needs, and job is not secured considering the layoff happening at recent time.
I'd like to know if you have similar experience, how you handle this, or is it just the time I should leave to seek for better opportunity I can grow? Thanks!

My skill stuck at current job, should I quit?
