work
- Software Engineer ByteZero Sep 2025 – Jan 2026
proxy infrastructure · Rust, Go, Redis
At ByteZero I worked on a geo-targeted proxy service that resells upstream pools (Oxylabs and similar); clients query proxies by country for scraping and localization workloads. Triaged and patched the original Go collector, then rewrote it in Rust after the Go version leaked memory under long-lived load. The service refreshes the pool from upstream providers, probes liveness, and indexes geo metadata so the API can serve per-country selections. A typical snapshot tracked ~140k proxies across ~133k unique outbound IPs, with duplicate detection and health checks driven from Redis.
