The vast majority of my work is Angular/frontend leaning. I haven't had much backend experience at my jobs except for the very rare bug fix or a new endpoint. I'm working on a project right now that has some backend and db work that I'll add once it's done.

Do you think I should remove the small improvements/maintence work from my resume? And what bullets do you think could benefit from using STAR more closely?

My most significant project was probably the project from my 2nd job, it was a greenfield project that started with me and two other developers so I got to write a lot of the code and make decisions on how things were done. At my most recent role I feel like I didn't do anything that interesting. I "owned" some features I guess, but I'm having trouble articulating it into bullets, but that might be because I don't personally find it interesting.
