I work on high-throughput backend systems: queues, workers, and the observability you need when they start lying to you. Day job is email infrastructure at scale — warmup schedulers, IMAP sync, bounce processing, and the ClickHouse/Grafana layer that makes it debuggable.
Most of my open-source work is the same thing in someone else's codebase: throughput bugs, render/perf regressions, SDK edge cases, and the small correctness fixes nobody wants to chase.
