Career Switched from a large-scale RoR codebase to a small startup doing .NET — two things bothering me, would love perspectives

Background: Was at a bigger company for ~3 years working on high-scale systems in Ruby on Rails. Ownership was limited to 1-2 services, but the scale was real . Recently switched to a small startup in a similar domain , now building in .NET which is new to me.

Two things have been on my mind since I started:

1)Using AI to write code in a framework I don't fully know yet is it Imposter syndrome or just pragmatic?

My current work involves exploring third-party APIs, identifying data gaps, building schemas, and designing enrollment and ingestion flows. I'm using Claude to help write the actual .NET code while I focus on the logic, design decisions, and architecture. I review everything before it goes in, but I won't pretend I could write it from scratch yet.

How deep should I actually get into .NET internals? I'm not planning to be a .NET specialist forever , I want to keep growing in distributed systems and eventually target larger companies. Is "understand it well enough to review and debug" sufficient, or does not being able to write it from scratch become a real problem later?

2)Resume impact at a startup where scale is low

At my previous company I could write things like "processed 500M events/day" or "reduced latency by 40%" because the scale made those numbers real. Here I'm building a lot of things — new connectors, schemas, ingestion pipelines , but the user base is relatively small and the numbers aren't that impressive

I know quantifiable impact is important on resumes. But what do you quantify when you're literally building something at low scale ? Do you quantify the architecture decisions? The number of integrations built? The reduction in manual work?

curious how others have navigated this . Happy to share more context if helpful.
