50% throughput improvement with Go and gRPC is a standout bullet. iCloud infrastructure is serious scale. If you can hint at the scope (requests/sec, data volume) that would make it even stronger.

Rare to see Rust + Go on a new grad resume. Companies like Cloudflare and Discord would eat this up. Consider adding open source contributions if you have any — it seals the deal.

As a fellow new grad this is super inspiring. The stack (Kubernetes, Redis, Postgres) is exactly what backend roles ask for. How did you get up to speed on all this?
