- ▹Built a high-performance rate limiting service in Go using the token bucket algorithm, achieving ~26K req/sec with p99 latency under 35ms validated via load testing.
- ▹Implemented distributed rate limiting using Redis + Lua atomic scripts to ensure consistent token consumption across multiple nodes with zero race conditions.
- ▹Designed storage behind an interface enabling zero-change backend swap between in-memory and Redis; added IP-based auto rate limiting, rate limit headers, and memory exhaustion protection.
