What's a developer experience issue at work that makes you want to quit?

My manager decided that we need to use an “ETL NoCode Solution” they used it at his last job and he said its good.

we had one 45 min demo then gave feedback like it’s not granual enough, not enough control for our use cases, no tests etc.

Months later he tells me the contract has been signed and he wants me to lead the onboarding.

i do my best thinking ill get a raise since im taking on much more work and ill get good experience, i get a decent raise but not enough to make me stay.

the tool made me absolutely miserable tbh, the support they had was useless, they over promised on what it can actually do. the amount of tool-breaking bugs it had were also too many to count. e.g: changing the mysql version connector for one data point would break all other diff ones in use.

i gave the feedback to my manager and that i think we should cut our losses short and stop the migration. he decides to do nothing

i quit :)

You mean Jira? or other than Jira?

Legacy microservices that turned into a distributed network monolith. Ah yes let's use location service to make an http call to location service for some db data.

I'm not a developer but I dislike offering a bad experience to the ones we have.

I run a service that provides data, I've bent over backwards to speed it up.. but there's only so much I can do until another team moves the source somewhere better

Entire management and senior eng chain of the company fundamentally not understanding the work or the requirements needed for devs to succeed. This is a very large company you interact with daily. A major one.

legacy code base, no documentation.

Dynamic method dispatch done in an un-grep-able way. Gets me every time.

Data scientists writing terrible unmaintainable code
