I recently joined my team, and I've been sort of overwhelmed picking up this new tech stack which may be leading to some procrastination. I literally have to Google for everything I want to write. Twitter also has certain in-house technologies, which are pretty challenging to learn. I also started working on a critical project recently with strict deadlines due to headcount shortage.
I saw this as an opportunity to make an impact and am trying my best, but I wish I had more time to get acquainted with the stack. I feel like I lost a few days last week unraveling through the ambiguity and getting context, so I didn't make progress with implementation as much as I wanted to.
I am kinda anxious that I will miss my delivery in the first project which is not setting a right impression. In my experience, there is no excuse for missed delivery and it will treated as a red flag. It's a newer company for me and my org is revenue-generating. Given the phase Twitter is going through, this project is critical and hence I am hesitant to push back on the timelines too.
I also see mid-level and junior engineers on the project moving way faster than me right now, because of their tenure and familiarity with codebase and that can be disheartening.
Lastly, should I be transparent and discuss with my manager if I feel a few days haven't been productive? I don't see any way that will help.
