A friend of a friend works/worked at Atlassian and was apparently slogging through legacy JSP when working on Jira.

They have had a complete turn around the last 2-3 years. It's snappy and seems like they actually listen to the feedback forms I fill out.

GitHub and GCloud are now the painful platforms for me. Jira/Bitbucket are nice by comparison now (imo). I use all of these daily. I suspect that Google and Microsoft are suffering from internal push to do everything with Ai. It shows when they are shipping slop and having uptime issues.
