When starting a new job with a tech stack you are new to, how long do you have to ramp up? And what is a general timeline for ramping up (first commit, first task, hitting normal velocity, etc.)?
Within a quarter I would expect you to be fully ramped up on our stack. There may still be plenty of one off process stuff you won't know, but you should be on par with others at your level on the codebase itself
First commit on day one ofc
In my team about 6 months to proficiency, 12 to hit your full speed
Start with small tasks, gain the team’s trust, take bigger tasks. Take big tasks within a few months.
