WHAT WE ARE LOOKING FOR

You should be proactive, able to make sensible decisions and comfortable working without constant supervision.
⠀
If something does not make sense, raise it.
⠀
If the UX can be improved, suggest it.
⠀
If Claude Code produces something poor, fix it rather than accepting it.
⠀
If a feature is not properly tested, it is not finished.
