SDE-2 at Amazon, on the team behind Amazon Relay — customer-facing systems that take very high TPS, where milliseconds and correctness both matter. Off the clock, I ship complete products end to end.

About

I work on customer-facing systems at scale — the kind that take millions of requests, can't afford a bad p99, and have to keep shipping while they're being rebuilt mid-flight. I like the work because every decision shows up in latency, error rate, or someone's day. On weekends I scratch the same itch in miniature: a full product, end to end, alone.

Shipped, end to end.
