I am a developer in a one of the Big 4 tech companies.
I used to be very good technically, then I joined my current team, which is using a totally new tech stack. I am learning it and I am doing well.
My manager knows nothing about coding.
They think that I am ready to be nominated to a senior developer position.
I am not confident yet, I know I am doing good, but I also know that I not 50% of control in the new tech stack. I have been experts in other stacks and I know exactly how it feels when you know all ins and outs of it.
The seniors in my company are so strong, I just don't see myself at this time at their level. However, I have the motivation to be one of them.
How can I tell my manager that I am not ready yet to be nominated, without putting myself down?
